Description Roberto De Renzi 2005-03-02 02:16:35 UTC
I think this might be related to other instances of server crash like 
659 1390 2496.
Symptoms: X freezes and the system shuts down. The console is not responding. It
is not possible to abort X with CtrlAltBackspace as it usually is.
I cannot log into my machine even with ssh from another machine. Hence I have to
force a restart by hardware reset.

 This happens to me reproducibly when trying to look at specific e-mails with
Mozilla, but also, not as reproducibly, when moving the Mozilla window.

Xorg.0.log ends on 
Fatal server error:
Caught signal 11.  Server aborting

The corresponding lines in messages, starting from last regular operation to
restart, are

Mar  2 10:02:19 pc34 su(pam_unix)[4272]: session closed for user root
Mar  2 10:03:53 pc34 syslogd 1.4.1: restart.

A couple of times I got a warning at startup saying that the CPU shut down
because it was too hot (however the air from the fan was cool and during the
subsequent startup - a couple of seconds later - dmesg  reported 51 C)

System: Dell Inspiron 8600 with ATI Mobility Radeon 9600 M10

starting with the snapshot, on linux systems, the X server can print
its own backtrace when it crashes.  please confirm that these bugs are still
valid with or later, and if they are please attach a the server log
from the crash.
Comment 2 Adam Jackson 2006-04-15 05:38:22 UTC
reporter, please verify that this is still an issue for you with a reasonably
current X, and if so please attach the X log from the crash.
Comment 3 Timo Jyrinki 2007-02-22 14:26:33 UTC
Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
