Public bug reported:
Hello
Could I first say that I'm still rather new to Linux, I appologise if I
report this bug incorrectly, I'm willing to listen to any comments.
I upgraded my girlfriends computer from Edgy to Fiesty and its been
having having random "crashes", there doesn't appear to be any sequence
to trigger it off (it can happen sometimes 5 time in 1 hour, or maybe
just once a day). The whole system doesn't freeze, instead only certain
processes appear frozen (mainly X and GUI programs). For example once
the crash happens I can't open a new terminal window in X (existing
terminals and open programs worked with limited effect) and the internet
cuts out. I have to press CTRL+ALT+F1 to get a new command line. Once
logged on I can do anything except execute super user processes (like
trying to restart gdm).
The system is such that I'm forced to resort to SysRq to restart my
computer safely. I've tried to SysRq kill all process/send SIGTERM to
all processes except init/send SIGKILL to all processes except init/call
oom_kill/make nice realtime processes. None seem to recover the system
to full operation :(
I've included a tracedump for you to see, I suspect wpasupplicant is
causing a problem (or possibly ndiswrapper and wpasupplicant)
Our computer is a P3 (coppermine) 800MHz, 256Mb ram, fiesty, D-link
DWL-G520+ Wireless PCI Adapter (not the best stats, but I'm afraid we're
not that well off). Also this might be important: when I upgraded from
edgy I couldn't get ndiswrapper from the repository to work, so I
downloaded it from the ndiswrapper website and installed it from source
(version 1.47 currently).
I've also run memtest and no errors found and checked hard drive for
errors and no bad clusters. I hope you can help me, otherwise we might
have to buy windows XP for this computer, its not a nice thought :(
