Hi all,
I've been having a few problems recently, since the move to EGCS, and I
finally caught my box in the act, with a core dump...
My system is running -CURRENT (version detail below), with no changes
other the Richard Seaman's LinuxThreads patches. It's a UP P5-233,
which is an overclocked 166. dmesg, mount and kernel config attached.
Yes I know, no overclocking, but the system has been stable for 19
months. I'll clock it back and try again if people suspect hardware,
but first read The Whole Story:
1. The first kernel which I built with ECGS, no frills, on 5 Apr 02:30
(GMT+2) after the EGCS import (once the world seemed to be building
again), I did the usual make buildworld, make installworld, config, make
depend, make and then make install. The system paniced within a few
seconds of the new kernel being installed. Major adrenalin rush since
the new kernel was not there because of softupdates...
2. Apr 5 23:00, rebooted on new world and kernel with "-O -pipe
-mpentium". Full ports rebuild with these flags.
3. Spontaneous reboot on 9 Apr 02:38, with some 'calru: negative time'
messages (from Apache) in /var/log/messages and some 'clientReadRequest:
FD ?? Invalid Request' messages from squid, neither of which I have seen
before, over the previous 24 hours. System idle.
4. Apr 12 00:55, rebooted on new world and kernel with "-O -pipe
-march=pentium", following tips from freebsd-current.
5. Apr 19 13:45, spontaneous reboot, system idle, following one
"clientReadRequest" error plus the following (note the block number?):
Apr 19 02:12:22 shale /kernel: wd0s1f: soft error reading fsbn 7414628
of 7414626-7414627 (wd0s1 bn 8375972; cn 14772 tn 3 sn 59) (status
58<rdy,seekdone,drq> error 2<tr000>)
6. Apr 21 20:00, rebooted on new world and kernel following new_bus.
7. Apr 29 17:30, paniced to debugger, following a large number of
"clientReadRequest" errors from squid. Finally got a core dump.

Written down from kernel debugger: tsleep+0x1b.
I have the core and kernel if anyone is interested. I can't put them up
for FTP, but maybe John Hay can let me put them on internat.freebsd.org?
Options:
1. Processor finally suffering from effects of overclocking.
2. UDMA IDE drive dying (squid cache is on the IDE).
3. Something doesn't like EGCS.
4. Something doesn't like -mpentium/-march=pentium.
5. I'm a moron.
Like I said, I'll clock the machine back if needed, but these problems
have only been around since the switch to EGCS, so I don't suspect that
overclocking is the problem. I do have my suspicions about the IDE
drive. (5) is always a option... :-)
Regards,
-Jeremy
