A tyan AMD64 opteron machine functioning as a usenet gateway really
pumps some traffic a day (http://newsgate.newsserver.nl)
Incoming traffic comes through a optical gig-E card (acenic)
and local traffic is fed to our spool boxes through cupper gig-E
(tigon3). Machine uses adaptec onboard scsi disks.
At first i thought i had a hardware problem since no kernel would
survive longer than 30 hours. Ofcourse i ran memtest for a couple
of days. Than i compiled 2.6.12-mm1 and this kernel surviced 18 days
without a problem.

reboot   system boot  2.6.12-mm1       Sun Jul 31 09:47          (01:48)
reboot   system boot  2.6.13-rc4-git2  Sat Jul 30 18:29          (17:07)
reboot   system boot  2.6.12-mm1       Sat Jul 30 14:12          (04:14)
reboot   system boot  2.6.13-rc4       Fri Jul 29 14:16        (1+04:10)
reboot   system boot  2.6.13-rc3-mm3   Fri Jul 29 12:17          (01:50)
reboot   system boot  2.6.12-mm1       Thu Jul 28 00:06        (1+12:09)
reboot   system boot  2.6.13-rc3-mm2   Wed Jul 27 22:27          (01:36)
reboot   system boot  2.6.13-rc3-mm1   Wed Jul 27 11:22          (12:41)
reboot   system boot  2.6.12-mm1       Sun Jul 17 15:51        (9+19:29)

Machine does have serial console (and remote powerboot) but no logging
possibility (portmaster1). When it crashes i think most of the times it
has something to do with IRQ.
2.6.13-rc4-git2 stopped working with the following notice:

Jul 31 03:28:18 newsgate kernel: hw tcp v4 csum failed
Jul 31 05:56:59 newsgate kernel: NETDEV WATCHDOG: eth3: transmit timed out
Jul 31 05:56:59 newsgate kernel: tg3: eth3: transmit timed out, resetting

Serial console kept spitting those messages but it gave no prompt
anymore. remote powercycle was needed to get it back.

Do we not have the oops output for this crash?

Is this issue still present in kernel 2.6.19?

Comment 9 Adrian Bunk 2007-02-22 09:42:19 UTC

Please reopen this bug if it's still present with kernel 2.6.20.
