I got this oops while running 2.4.4-ac6 and trying to open a file to edit with
vi. I have had this happen before while I was opening a text file but I
suspect that it is just coincidence. I have included the ksymoops output for
the oops and also my kernel configuration. If there are any patches or if
there is any more information that anyone needs then please let me know.
Thanks,
Sean
ksymoops info:
ksymoops 2.4.1 on i686 2.4.4-ac6. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.4-ac6/ (default)
-m /usr/src/linux/System.map (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.
