That is. Just tried. Details below.
mount options:
/dev/scd0 /mnt/cdrom iso9660 noauto,user,gid=100,unhide,mode=0444,ro
Device is a cd-recorder:
SCSI subsystem driver Revision: 1.00
Uniform CD-ROM driver unloaded

Oops is the oops below (slightly formatted). It's reproducable, though
i'd like to avoid the reproduction.

No filesystem damage. Which is always good.
The isofs had compression compiled in, but the zlib_inflate module
wasn't installed. I just copied it into modules/2.5.10/kernel/lib.
Parts of the config caused the oops (i'll mail the whole
if you think i cut too much):

The last line is strange, the zlib_deflate was installed!
