4191 and 4349 2d corruption problem

[Andy Mecham]

So far, no repro. Can you give me your distro/machine/card/XF86Config?

Distro:
any of: RH 7.3, 8, 9

Kernel:
all stock RH kernels (both SMP and UNI)
linus's 2.4.20 (other vanillas not tried)
-Do you need the output of lsmod?

Machine:
Supermicro X5DA8 MB (Intel E7505 chipset)
dual 2.8 Ghz CPU
1 Gig registered ecc RAM
U320 scsi (aic79xx based) (onboard the MB)
intel e1000 ethernet (onboard the MB)
DVS SDI I/O card (www.dvs.de)
-If you need more detail, I can post a lspci or other infos.


Card:
PNY Quadro4 980XGL

XF86Config:
see attached.

It can take some time to reproduce. (usually less than 20 minutes for the flow-blown 'eww' black corruption, but you can see hints of things (a little more flicker than usual in a rapidly updating dialogue, for example) before the full-blown eww)

The screenshots were taken on RH8 with the stock (updated) 2.4.18-24.8.0 kernel, both SMP and UNI

So, were you able to reproduce the problem yet? Waiting for new hardware? =)

[Andy Mecham]

Actually, no - both test cases ran for several hours without causing any corruption on the systems I checked. I'll push it out to some other systems today - i've got some ideas about it now.

I didn't get to it this weekend, sorry...

Well, here is more corruption.
XF86Config has not changed, nothing has changed, however, this is the corruption I get.

To be clear- I was not running any program in particular, not even something that updates the screen often.

Here is the script used to harvest this information

Assuming you guys are in the SF Bay area, I'm happy to take this computer to you to play with for a few days.


echo "-------- lspci output follows --------" > machinespecs
lspci -vv >> machinespecs
echo "-------- lsmod output follows --------" >> machinespecs
lsmod >> machinespecs
echo "-------- uname -a output follows --------" >> machinespecs
uname -a >> machinespecs
echo "-------- output from 'cat /lib/modules/`uname -r`/build/.config' follows --------" >> machinespecs
cat /lib/modules/`uname -r`/build/.config >> machinespecs

Thanks for all the info!

Have you guys been able to reproduce the problem yet?

I'm willing to bring the machine over to you guys to play with for a few days to help solve the problem, if that would help (you'd be free to wipe the harddrive, etc)

More information:

Offscreen rendering is uneffected by the corruption.

When you get it into this state, you can open up a new window, and certain parts of the new window (most/all of the background part of the window) will be transparent. i.e. black text will appear as black, but as if the window's canvas was translucent.

The screenshot was taken on RH9.0 running kernel 2.4.20-9smp, using 4349

Sorry to keep bringing this up, but, is there any word or reproducing this problem?
