Xorg crashed with SIGSEV in nvidia_drv.so(_nv001652X+0x21) on VT switch.

[LimCore]

Binary package hint: xorg

On VT switch sometimes the computer freezes / GFX dies. Happened 3-4 times so far during 3 months.
Ubuntu 9.10, NVidia GeForce GTS 250, Quad Core, 64 bit.

The main error message(s)
Xorg[1662]: segfault at 8 ip 00007fa2aff0756f sp 00007fff1e5e1620 error 4 in nvidia_drv.so[7fa2afebd000+3ac000]
3: /usr/lib/xorg/modules/drivers//nvidia_drv.so(_nv001652X+0x21) [0x7fc04f421851]

*** Symptoms ***
This time upon more testing I noticed that the computer was in fact running,
but the GFX was dead.
alt+ctrl+f1 throw me to VT1 where I was able to login as root, but all the time the monitor was showing blank screen.

But the GFX card did detect I was in text-only mode, because in this mode it always has fans running at maximum speed (which itself is probably a bug in nvidia power saving, but that is another topic).

So - it's more like the GFX output died in a way that I was not able to restore while trying (blindly) to killall -9 X nor /etc/init.d/gdm restart.

At some point keyboard died (caps lock not reacting) but SysRq's seem to fix that.

I have a feeling this *may* be related to RAM being full and computer swapping during switching (but perhaps totally not).

There are pulse audio errors always when this crash occurs, but they may be just related to the VT switch, not to the crash happening sometimes on VT switch, dunno.

Remaining Xorg.?.log of 4..7 have same backtrace; they are probably result of attempts to alt+ctrl+f7 alt+ctrl+f8 while the screen/gfx where unable to work normally.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
