I too continue to have problems with OS4 final. I have a uA1c with 256 MB of memory. I installed it on a freshly formatted partition. When I first tried it, it was so bad that I reverted to using prerelease update 4 which for me has been rock solid. I kept hoping that I would read enough here to understand what all the pitfalls were withoug having to post my own message about my roblems, but I guess its time to explain what I am seeing.

First. When booting up, at least half the time I wind up with a black screen. Things seem to be progressing as they should, but I never get to the point where
startup-sequence is running much less workbench, and I'm left with a black screen.

Second. I have an ARexx script that I run to do a full backup of my system. What it does is that it creates a new directory on one of my external USB hard drives with today's date in the name and then proceeds to issue a commands of the form:
copy partition-name: USB:date/partition-name all clone quiet
for each of the partitions on my internal hard drive. I have NEVER gotten this script to complete. It always fails when executing one of the "copy" commands. Typically, what happens is that my system locks up. That is, I can still move the mouse around, but I cannot launch any applications from the task bar at the bottom of the screen, and I do not get any Guru meditation message.

Yesterday, I decided to see if I could get better results by disabling Petunia. So I went into sys:kickstart/kicklayout and commented out Petunia.library.kmod and rebooted. Now when I run my backup script it still fails when doing one of the copy commands but I now get a guru which reads:
Guru Meditation: 80000003
Task 0x6ff71f00 ("UHCI Controller Task Unit 0')
generated an error of type DSI (Data Storage Interrupt)
on address 0x012155ac
Redzone was not damaged
Stackpointer is inside bounds

I'm very frustrated. I'm not using third party software such as MUI, IBrowse, etc., just plain vanilla stuff which comes with OS4, and since my last experiment completely disabled Petunia I don't see how that could be an issue. Am I the only one still having problems with OS4 Final. Any sugestions would be greatly appreciated.

Thanks.
Ned

@Ned
Without serial output I can only guess and my guess would be bad RAM.

Please test your ram with the memtester:

@Ned

It will have nothing to do with petunia, as you're using "just plain vanilla stuff which comes with OS4" then it will all be native ppc programs except for the ARexx bit, maybe your using some function from a third party arexx library. I suggest trying a dos script instead.

something like this:

cut "`date`" w 2 >t:temp
set today <t:temp
makedir usb0:$today
echo Copying dh0:... noline
Copy dh0: usb0:$today all clone quiet
echo Done.
echo Copying dh1:... noline
Copy dh1: usb0:$today all clone quiet
echo Done.
delete t:temp force quiet
unset today

Edit: Can't use a 'less than' that's needed in the script as it stops everything after it being displayed here :( replace the '&&' with a less than to get the script working.

(edit: should be fixed now)

It may be that your sole purpose is to serve as a warning to others.

You are not the only one.

I get that uhci controller error infrequently, i`ve just commented out Petunia to test also.

My board and ram have just recently been tested by Amiga Center France and passed.

Yeh, I get this too. I can just be leaving the system alone, downloading a file, and I'll return to a Grim for UHCI.

1st - getting very often a blank screen.

Had this also very frequently with my A1XE/800 MHz/Radeon 7000. Changed flash battery, minimized WBStartup progs etc. No help until I decided that it has something to do with the new KickStart/ATIRadeon.chip. Replaced it with the update4 one. Never had problems since.

With the price of at least overlay! Well, version 52.5 works here.

@AmigaPapst

I have just finished running MemTester and it has made for loops through my memory without finding a problem, so I don't think this is it.

The following worked for me. Can't find the specific thread where it was discussed (it was buried within a similar discussion).

Go to Devs:Monitors drawer and check the Tooltypes for your Radeon icon. If it says INTERRUPT=Yes then try setting it to (INTERRUPT=Yes) and see if that makes any difference.

I compared my settings with my OS4 update #4 settings and found that it was set to (INTERRUPT=Yes) in my OS4 update #4 settings. I have not encountered the black screen since I changed my setting to (INTERRUPT=Yes) in OS4 final update on Feb 3, 2007 (approx 9 days ago).

@Ned
Was any of the above helpful?

This thread needs a bump anyway. Ned won't
be able to do much of a demo of OS 4 final at
the next MCCC users group meeting in March
if he can't get it working a little better.

Commenting out this tooltype is equivalent to listing the tooltype as "INTERRUPT=NO", and has solved the issue for a number of people.
The above is true at least for onboard radeon 7000.
The side effect, so to speak, is that hardware interrupt trigger is disabled and interrupt polling is enabled, which is slower.

I remember I had problems with crashing USB stack too, and I found that the problem was caused by:
- incorrect vcore setting
- floppy cable being plugged in the wrong way around (ouch!)

This may be true. But amazingly INTERRUPT=NO solves the problem of AmiPDF scrolling interrupting the AmigaAMP/Tunenet/AmiNet Radio sound.
