PROBLEM: 2.6.1 perhaps ext3 or fat releated crash

[Petri Koistinen]

Hi!

Kernel crashed (jammed) and I had to reboot manually. I had digital camera
attached when booting. Camera has vfat filesystem on MMC card. (/dev/sda1
on /mnt/camera type vfat (rw,noexec,nosuid,nodev,user=petri)

More info on (System.map-2.6.1, config-2.6.1, kern.log, ksymoops.txt,
vmlinuz-2.6.1): http://iki.fi/petri.koistinen/kernel-oops-2004-01-20/

ksymoops 2.4.9 on i686 2.6.1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.1/ (default)
     -m /boot/System.map-2.6.1 (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
