Oops

[Mark Hindley]

Hi,

I have been experiencing periodic hangs on my Thinkpad 560E with the
last few kernels. It usually happens when changing consoles.

Finally, I got an oops today rather than a hang requiring a reset with
nothing in the logs.

Exactly the same think provoked it: changing VT

Let me know if you want more info.

ksymoops 2.3.4 on i586 2.4.15-greased-turkey.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.15-greased-turkey/ (default)
     -m /boot/System.map-2.4.15-greased-turkey (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
