An nnrpd just oopsed and took the news filesystem (the only reiserfs fs on this box) down with it (everything touching it D-states).

Oops:

ksymoops 2.4.6 on i586 2.4.21. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21/ (default)
-m /boot/System.map (specified)

Jun 22 13:52:43 loki kernel: EIP:    0010:[<c0092df4>]    Not tainted 

And the EIP is prior to kernel start which is also very strange. On the other hand the address c0192df4 is somewhere inside reiserfs code, so it looks like a single bit error, I'd say.

Can you run memtest86 for some time to verify that your RAM is OK? (hm, and the oops got twice to the logs which is pretty strange thing, too, never seen anything like this).

I'll say! Looks almost like it JMPed to a null pointer or something.

I think it unlikely to be RAM problems given that the problem happened shortly after upgrading to 2.4.21; this was about half a day after I rebooted it because it threw a pile of never-seen-again, un-syslogged SCSI abort errors at me (sym53c875); and *that* was a few minutes after I rebooted into 2.4.21 for the first time.

All my other boxes love 2.4.21, but this one dislikes it. (Of course it has to be my second-most-critical server... ah well, the NFS problems in 2.4.20 bit my most critical server and my home directory both, so I guess this is less unpleasant.)

Did that last night; no problems reported. (Not really surprising.)

That's my weirdly broken syslog config. I've never got around to fixing it; it only happens with kernel messages and I don't get all that many of those.

No, if it'd jumped to a NULL pointer, we'd see 0 in EIP.

Hm, so first there were some scsi problems and then reiserfs oops?

Actually since the RAM is good, I see no good reason for this to happen. (actually I see no good reason for valid code before _text, either).

I wonder if 2.4.21 constantly crashes like that for you, then?

JMPed to ((long)NULL)+1 or something then :) the fact remains that it's not somewhere that even a memory error would make us likely to jump to.

Different boots. I upgraded, the first boot crashed within five minutes with weird SCSI errors, so I rebooted again and this happened six hours later.

I'm willing to write off the SCSI errors to the shock effect of having just been powered down for the first time in a year (the shutdown scripts didn't quite work and the reset button is disconnected).

No obvious sign of it:

9:34pm up 1 day 22:30, 14 users, load average: 0.09, 0.12, 0.16

(it is of course waiting until I am hundreds of miles away. *Then* it'll crash.)

The EIP isn't zero or 1, you've got a bad null pinter dereference at address 1. You get this when you do something like *(char *)1 = some_val.

The ram is most likely bad, you're 1 bit away from zero, but you might try a reiserfsck on any drives affected by the scsi errors.

Ah. That does sound like either bad RAM or scattershot corruption.

Done that, no problems found. (Most drives are e3fs.)

2.4.21's crashed once more since then, network driver death; I'm probably going to revert to 2.4.20 on that box, which ran perfectly since three days past 2.4.20's release. (However, several other boxes had problems with 2.4.20 which were cleared up with .21... you win some, you lose some. I'd say this has been a net gain.)

I'll see if 2.4.20 has the same problems; if it does, then I agree, the RAM's probably had it.
