Subjectkswapd oops - advice on debug
Date
Hi all,

Merry Christmas! Hope you all had a good one.

I need advice on debugging kswapd oops. I get these on every kernel from
2.6.5 -> 2.6.9. 2.6.4 performs OK. I am currently building 2.6.10 to try
this as I see in changelog there was some work done in this area. The oops
is always kswapd writing to and unpaged area (I believe).

I have tried everything... 2.6.4 just works. 2.6.5 -> 2.6.9 can run anywhere
from 7 to 90 days before I get an oops. After an oops the system stays up,
but I cannot login on any terminal and new connections (pop3 etc.) fail.

I can't really give much info, as it all varies, but I really need to sort
myself so I _can_ give you all correct information. This is also my gateway,
so I cannot play around much on this box.

I have new memory coming, so that will also aid to debugging - current memory
is 128MB with 128MB disc swap and 260MB file swap:

total used free shared buffers cached
Mem: 126872 123032 3840 0 19088 49956
-/+ buffers/cache: 53988 72884
Swap: 398648 1452 397196

The box runs httpd, ntpd, ssh, nfs client, sendmail, spamd, ircd, pop3,
iptables/NAT, DNS cache server.

File system ext3. Minimal hardware:

:00.0 Host bridge: VIA Technologies, Inc. VT82C585VP [Apollo VP1/VPX] (rev 23)
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C586/A/B PCI-to-ISA [Apollo VP]
(rev 27)
00:07.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06)
00:07.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 02)
00:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 10)
00:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 10)
00:0b.0 VGA compatible controller: Matrox Graphics, Inc. MGA 2164W [Millennium
II]

No sound, parport, USB etc. Barebones.

Any help on what to do to trap this properly much appreciated.

Thanks,

Nick
