It's probably a JFS issue, but I thought I'd report this in case someone
is collecting and correlating filesystem corruption messages (Alan?).
Here is my sad story.
I have an Athlon 700MHZ, 256mb ram, AIC7XXX w 2/U2W drives system. I've
been running JFS on a small partition for a few weeks, JFS 0.3.1 under
2.4.5, 0.3.3 with 2.4.6-pre1 and yesterday I tried 2.4.6-pre2 with jfs
0.3.4.
I rebooted into the new kernel, and noticed one of those Red Hat [FAIL]
messages that pops up during the rc/init stages. It's a config problem
I've had for months, nothing new, but I decided I'd take care of it. I
logged into the console, ran emacs and it segfaulted. I ran 'dmesg' but
there was nothing (I was expecting to see an oops). I ran emacs again,
segfault. I tried logging in to another console, hang.
At this point I hit sysrq-T, and of everything that spewed by, I noticed
one process (which had scrolled to far off the screen to see the PID)
with a whole lot of
<dbdbdbdb> <dbdbdbdb> <dbdbdbdb> in the stack trace.
At this point I did sysrq-S-U-B and rebooted. End of story.
My filesystems were severely f***ed at this point. A total of about 60
seconds running this kernel and I was dead. My OS partition was
trashed, about 1/2 of it was unrecoverable. My home partition fared
better (good luck) but still had plenty of trashed inodes.
I've never had problems with any kernels before this...
That's my story,
David

I get as far as 'using jfs' and delete them

Understandable but FWIW they have apparently passed a night of
stress-kernel (cerberus) testing on the latest jfs..

rm -rf not working correctly is a kind of show stopper bug ATM though.
Hopefully it can be fixed soon.

with too many files inside of a directory this was a bug also under
AIX 3.2.5, and could be used for any kind of DoS.
Just with AIX 4.1.X this bug disappeared and we also got the
possibility to use a block size smaller than 1024

Andi,
The rm -rf problem is our topic priority and should be fixed in less
that a week.
