When trying to ls on cdrom mounted on scsi1 (Plextor CD-ROM), mount goes
okay. "ls" /mnt/cdrom results in
"oops" - same as a previous post. The ls did work
once with a cdr disc

Hi Vincent and Tony,

Hate to spoil the fun :( but, try the patch Tom Leete commited on Saturday
november 18th.
Since your Oopses are related to get_joliet_filename(), this might just do
the trick?

there is a buglet in fs/isofs/namei.c, corrected in test11-final.

Hmmm.

after I mounted the CD-ROM. Moving to the directory the CD-ROM
was mounted on, it is empty !

Going back to 2.4.0-test10-final cures the problem.
