i got an kernel oops in d_lookup
[2.]
when running image conversion (100% CPU usage, about 2-3 MB file copying
from local CD-ROM to local ext2 fs on SCSI drive in about every 3-5 minutes
then imagemagick's mogrify activity over copied file (again on same local
ext2 SCSI filesystem)) i experienced kernel problems: OOPs in d_lookup
(see below log entries).
symptoms were as follows:
- after first messages, system was running but any new process causes one
OOPs (first was produced by ical - as can be seen) and did not start
- when switching to console and pressing <Alt+Ctrl+Del> last oops to
console has been printed and machine went totaly frozen
no such error occured during usage of previous 2.2.13-preX kernels (tried
pre8, pre9, pre11 and pre14). also nothing similar when using 2.2.12 and
earlier (this do not means i did not encounter no errors at all :) - see my
previous posts regarding instant freezes).

image conversion program (probably) - i.e. intensive operations on ext2
filesystem?
when running connversion, error occured about 10 minutes after start of
conversion. but when running conversion second time (after reboot), to see
whether i can reproduce this crash, after about 4 hour is system still up
(and converting) without any oops messages.
