Your system would hang immediately if it's on edge (at least for audio cards).

The problem is not only one for sure. 1-Audio+ethernet 2-vcore or heat

I'll have to go for number 1 on this.

My VCore is set correctly and I have a chuffing great heatsink and fan in direct contact with the CPU.
:edit:
memory also fine and heatsink on SDRAM too.
:/edit:

In fact, I've had DNET crunching, 3 Debian ISOs downloading, and Family Guy/American Dad/Simpsons episodes playing (with no audio) via MPlayer since 17:47 - no lock up.

As you say, both me, you and other people have set their
VCORE and have good fan's so it cant be that.

Ok maybe it worked for IKIR but believe me this is the
4th fan solution and VCORE i have already done for ages.
And no overclocking.

And as others i used ATC to download files, use DNET as
same time and it would go for a long time without any
problems. Its only when i stream/play music that the
total freeze comes that people describes.

Besides there must be some other way to stress the system (heatwise) other than by playing music and using the ethernet?

This summer is turning into a real scorcher and my Amiga is camping on the second floor of my house where it is easily up to 30C at times during the day but it just runs 24/7 doing DNetC and whenever I manage to sit with it. I don't even notice this problem since I hardly ever play music while I'm downloading a mess of files at the same time, at least not for any length of time.

Sorry to jump in so late here, but I'm trying to reproduce this.

It seems like the current consensus, aside from VCore, bad RAM, issues, are some sort of conflict or problem exxagerated when network and audio are used at the same time, correct?

So....if I were to use AmigaAmp in looping mode playing continuously, while downloading the Fedora Core 4 ISO images, this is expected to cause the lockup?

(Sorry, it's a LONG thread right now, and I didn't see a simple: "How to Reproduce" summary.)

BTW, first time I've ever plugged speakers into the A1 so far (long story, but have 7.1 speakers + USB KVM that does only 2.1 audio sharing..).

System:
'fixed' XE G4-933MHz
SB Live sound card
pre-release update 3
512MB single stick of RAM, memtester checked
Jumpers checked
USB keyboard and mouse through KVM

Currently using mpega.library from OS4depot, OS4 version.

Anything else I can do to try to reproduce this? (I'm also using IBrowse with 6-7 tabs open at same time, plus WookieChat).

EDIT- Oh, and I'm downloading the ISOs (all 4 at once, ETA ~3-4 hours) over samba to a remote file server..

Ok, confirmed. Hard lock-up, entire system freeze after a bit over an hour.

Worse, I was typing a VERY long 'Amiga History' type of reply in IB when it happened, that's lost. Agh!

Keyboard not responsive (USB or PS2), unable to fast or cold reboot, total system lockup with a hung 'note' in the speakers in mid-song of Jimi Hendrix
"Are You Experienced?"

Hmm. Has anyone tried this with a serial cable attached and in debug kernel mode? (Gonna go hunt up a serial cable and see if I get ser output..)

_________________

@wegster
Ok, trying again. Serial setup was fun, considering I couldn't find a known good cable so had to piece one together. BTW, serial 0 (debug output) for anyone following along at home is the port closest to the PS2 and USB ports.
In uBoot:
setenv stdout=serial (the default is stdout=vga)
setenv baudrate=115200
saveenv

then set your comm program to 115200 8-N-1.

So, trying again, with serial output this time, using the debug kernel.
I seem to recall a uBoot tutorial somewhere, anyone have a link? (want to change debug levels and see what else may be available)

Start time: 12:30am EST
Apps running:
dnetc (same as last time)
AmigaAmp in repeat mode
IBrowse downloading Fedora Core ISOs 1-3 simultaneosly
netmon

Anyone know of a standalone CPU monitor (besides CPUClock.docky, or have source for it so I can take a look? I don't need another clock ) ?

Crash time: 12:50am EST.
Nothing output over serial, looking for uBoot tutorial now, think it's at IntuitionBase, will try a few different options and see what can be seen.

Same behavior, hard system lock with high pitched whine coming from speaker.

Congrats on enjoying the same fun as us

If anyone out there also cannot follow this thread, I've done a couple of summaries because it is big.

Post #159 here & post #265 here. Of course there's other details elsewhere, but these give you the basic idea.

I think WookieChat is a stability killer. Try your tests without it up.

@FuZion
Heh, thanks
IB was offline, back up now, but nothing I saw about changing debug levels for the kernel (other than you can). Anyone know what valid OS4 debug levels are
, and if they can be changed while the system is running/how? (assuming so..)

Ok, it's 3:26am EST and I need sleep. Leaving IBrowse up, and playing AmigaAmp over SMBFS in loop mode, will cehck it in the am. That will generate 'some' network traffic' (~27K/second according to NetMon) but not as much as downloading ISOs.

Will see what happens.

@jahc
Ok, WC killed, although I haven't had any stability problems obviously caused by it.

Ok, no clue what the different OS4 debuglevels are, but logging at debuglevel 9 over serial at least. If somoene has a link to the different debug levels, let me know.

_________________

@wegster

Whoa, long thread indeed. I just have one question: do these problems apply to the micro-A1 too?

A.

@wegster
Got os4 debug going at debuglevel 9 over serial.
Crashed at : 3:57am EST

Nothing useful in serial output, appears to just be task scheduling:
[_impl_AddTask] Calling HAL_TaskPreStart
[_impl_AddTask] Task added to ready list
[_impl_AddTask] Task = 0x021B0578, ETask = 0x021B0810, Context = 0x02538FF0
[_impl_AddTask] Stack bottom = 0x029E98A0, Stack top = 0x02A0989C, Stack pointer = 0x02A09860
[_impl_AddTask] Calling HAL_TaskPreStart
[_impl_AddTask] Task added to ready list

I WAS, downloading a single ISO during this, as I was hoping to get something out over serial at the crash, but evidently not.

Will retry again without downloading the ISO, but still using SMB with some network traffic.

I think that just about sums it up, if anyone thinks I've missed something, let me know.

I can't reproduce this with my dialup connection but dialup speeds don't stress the system very much. I read you list of things that have been done to track down the cause and just wanted to make a suggestion.

Has anyone who can easily reproduce the crash tried ruling out disk DMA or disk access in general? Does it happen if hard-disks are set to PIO mode. Can the test be run with a download going to RAM: and the sound file being played located in RAM: ? It's just a thought since it would be nice to be able to narrow the problem down as much as possible.

It wasn't happening on linux untill recently, kernel 2.4.27
And it started to experience crashes during the boot , mostly with 2.6.9(the machine just stops respnding).
Downclocking from 800 to 600 MHz didn't help.
I'll try to disable the preemtive m/t of the kernel.
I hope my A1 isn't dying slowly...
I'll renew the themal paste between cpu and the heatsink next week to see if it helps (after the new kernel test).
The nest suspect is the psu.

Wow, THAT was a helpful comment. Xenic and others are trying to help at least.

Is a resolution or root cause known yet?

No?

Then no, the thread is NOT long enough.

Has this issue been added to the official buglist? And has the people behind both AHI and the TCP/IP stack been contacted?
I think i remember one of them made a comment here earlier on what could be the issue, but i have failed to find that thread again

Can't reproduce it with TuneNet... then again, AmigaAmp wasn't causing the problem beforehand (before I loaded up TuneNet) either. I'll keep testing.

Some PSUs have trouble because the PPC doesn't put much load on them. I certainly wouldn't rule it out in any investigation, as it shows up as odd crashes etc.

@wegster

Try kdebug "debuglevel 10"
