Bug #: 49815
Summary: nouveau segfaults in p_atomic_dec_zero
Classification: Unclassified
Product: Mesa
Version: git
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/DRI/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

Looks like I've been bitten by the same bug, or something similar.
Everything was working fine until I pulled in the latest mesa from git
and recompiled. Then gnome started going only into fallback mode. In
dmesg I was getting:
gnome-session-c[3618]: segfault at 100010001 ip 00007f0419ae0570 sp
00007fffd3204870 error 6 in nouveau_dri.so[7f0419a64000+495000]
When in fallback mode, if I ran glxinfo it would also segfault:
glxinfo[3729]: segfault at 100010001 ip 00007ffe31f49570 sp
00007fff22a85df0 error 6 in nouveau_dri.so[7ffe31ecd000+495000]
Going back to commit b328949a37fee7b0f68ed3e068ffc4426c083042 fixed it.
I'm afraid I have no backtrace but if someone can point me to some quick
instructions I should be able to try to get one in a few days.
Here is what lspci says my card is:
01:00.0 VGA compatible controller: NVIDIA Corporation G86M [Quadro NVS
135M] (rev a1)
I'm using a very mixed Debian testing/unstable/experimental, kernel
3.2.0-2, amd64, on a Dell Latitude D630 laptop.
(BTW, nouveau works moderately well on my box. I can run Gnome 3 but the
zoom animations look like crap, maybe because the card stays in
low-power mode. (I used to run the nvidia blob with Compiz, and I had to
deactivate power saving to get good animations then.) After about 20-30
hours of use I usually get some kind of memory corruption, or X locks
up, and I have to reboot. However, the 2d acceleration rocks, much
faster than the blob! Makes it worth it.)
Anyway, thanks to everyone for your great work! Greetings,
Andrew
