Subject: Oops in 2.6.25

Hi,

(please CC me in replies)

my current kernel just threw an error, see output from ksymoops below.
I've been using this version for quite some time now, this is the first
time this has happened. There have been no hardware changes lately. The
hardware itself is nothing special, it's a somewhat dusty Thinkpad. 

I hope I have included all relevant information, please contact me if
more information is needed.

Cheers,

Wolf


ksymoops 2.4.11 on i686 2.6.25.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.25/ (default)
     -m /boot/System.map-2.6.25 (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.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
