Hello, I'm facing strange problem with jfs /usr filesystem.
I cannot mount it in rw mode - kernel oops is generated, but "mount -r" works just fine.
fsck.jfs -f /dev/mapper/Linux-suseUsr works flawlessly => no error found.


The kernel is 2.6.5-rc3, jfsutils is 1.1.5, the /usr volume is created over LVM2 2.0.8
but metadata format is lvm1.


I'm unable to copy whole oops message, but the most important thing is (in my opinion):

EIP is at lmNextPage+0x1b/0x130 [jfs]
Process mount
Call Trace:
[<d8cf4c14>] lmLogInit+0x4f4/0x550 [jfs]
read_cache_page
mempool_free
release_metapage
lmLogOpen
dbUmount
jfs_mount_rw
jfs_remount
do_remount_sb
do_mount
handle_mm_fault
__alloc_pages
copy_mount_options
sys_mount
syscall_call

After booting 2.4.21-199 standard SuSe 9 kernel, it works OK (can be mounted in rw mode).
And then, after booting 2.6.5-rc3 again, everything is OK.


Best regards, Janusz
