Re: [SLE] Cannot determine why my 8.1 box keeps hanging.

It is 8.1? The kernel on 8.1 is faulty, if you have at least one reiserfs partition. You should enable "barrier=none" option in fstab for those partitions, or use the patched kernel they provided.
The symptom was a complete absolute sudden crash: every ting stopped, nothing in the logs, no network access, keyboard locked, num lock and cap lock led blinking --> ie, kernel crash signaling.
Often the HD led would remain on.
One more possibility apart from the other things you were told already :-)

Carlos and you other gurus: I was aware of the 8.1 kernel problem, and the first thing I did when I installed 8.1 was upgrade my kernel. However I did not know of "barrier=none" option in fstab. I now see it is is hinted at in SuSE's support knowledge base: http://sdb.suse.de/en/sdb/html/81_update_kernel.html but not really explained how to do it. I looked at "man fstab" and read Carlos'December post: http://lists.suse.com/archive/suse-linux-e/2002-Dec/0658.html I still have no clue. Could someone please show how my fstab table would look if I put in a "barrier=none" option in it.

I believe, IIANM, it is to be added to the kernel parameter line in grub or the append line in lilo. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org

Well, if you updated the kernel patch from suse, you don't need the barrier thing - actually, if you do it, mount will fail. They removed the code, so trying to use it produce a parsing error. It is a way of making sure if you have got the patched kernel or not. By the way, the patched kernel may have problems with nvidia cards: very very slow 3D - at least in my case.

True. From their point of view the patch solved it, I guess; the fstab
thing was never really documented - not for the average user :-)
The only doc I ever saw was this email, on this list - I'l paste it, it is
short and old:

Pity the archive has no body search - you'd found it. I just did on my copy ;-)

Ok, just for curiosity shake, here goes; I used: /dev/hdb6 / reiserfs defaults,barrier=none 1 1 And it worked. If your kernel is patched, mount will fail: so try it first on an auxiliary partition, not the root one. -- Cheers, Carlos Robinson
