oops under JFS

System: 2.4.6-ac2 + ext3-0.9.1 + jfs-1.0 (had to hand-patch bits) + raid5 fix
Athlon, UP, gcc-2.96-85 (RH), everything as modules.. (loaded modules at
time: vfat fat ide-floppy ext3 jbd nfsd aic7xxx sd_mod scsi_mod
nls_iso8859-1 jfs es1371 gameport ac97_codec soundcore nfs lockd sunrpc
mga agpgart autofs usbcore unix reiserfs eepro100 ide-disk ide-mod)

I filled a ZIP100 jfs directory by running mktemp lots. One nice thing I
noticed was that I had 97056 1k-blocks to play with (is the journal
dynamically sized?), but as the zip filled up (8 blocks left) mktemp
segfaulted and I got: "ialloc: diAlloc returned 28!",
"assert(iagno < imap->im_nextiag)", then the attached oops.

Any further info available on request.
