Subject2.4.5 + ReiserFS + SMP + umount = oops
Hi list :)

I just upgraded an SMP-machine from 2.4.4 to 2.4.5.
It's a
2xPII@300MHz
Asus P2B-D motherboard
128mb RAM.
unknown PCI gfx-card
Promise ATA-100 IDE-controller

Problem #1
I have 2 disk on the ATA-controller (30 and 45GB - both IBM) running a
Reiser-partition each.
I can do reiserfsck and debugreiserfs just fine and get an 'ok' back from
both ('ok' from fsck and 'VALID' from debug..). I can mount the
reiser-partitions, but - when I umount the first partition I get:
# umount /stuff (/dev/hde1)
journal_begin called without kernel lock held

I took a look at fs/reiserfs/journal.c and compared (diff) it to the same
file from 2.4.4 and found the line where the message is generated (line
423). The problem is that a diff on those two journal.c's revealed no
difference whatsoever which leads me to the conclusion that this bug might
not have so much to do with ReiserFS afterall.

These things worked fine in 2.4.4 btw.
back in 2.4.2 I followed the Changes and did an upgrade to binutils,
e2fsprogs and util-linux, and these upgrades should still be ok.


Problem #2
Certain keystrokes like ctrl+c does not work when logged in from the
console - only when logged in throuhg ssh. This is really not that
important as the machine only acts as a monitor-less fileserver.



If You need additional information - please let me know.

regards
/Rene
