[2.] Full description of the problem/report:
This is the second of two Oopses with 2.2.11 (in one day). They
both showed ext2-functions involved. The first, which I can't
report (new kernel compiled, but not running at the time), occured
while the Mutt MUA was reading a mailbox, this one while xcdroast
(its mydd) was creating an image file. The hard disk was /dev/hda.
[3.] Keywords (i.e., modules, networking, kernel):
file system, e2fs, ext2
[4.] Kernel version (from /proc/version):
Linux version 2.2.11 (root@christian) (gcc version 2.95 19990728 (release)) #2 Thu Aug 12 21:15:52 MEST 1999
