That kernel is very old, you should get the latest RHEL errata update 
kernel and see if that helps. There have been hundreds of bugfixes in 
RHEL kernels since that version.

Network broken in kernel level.

[Wang Penghui]

Hello, list,

Recently, i have messed up with the follow problem, i have two server
both with two ethernet cards. Here are them:

[root@db1 ~]# lspci | grep -i eth
05:00.0 Ethernet controller: Marvell Technology Group Ltd. Gigabit
Ethernet Controller (rev 18)
07:04.0 Ethernet controller: Intel Corp. 82541GI/PI Gigabit Ethernet
Controller (rev 05)

And they are running MySQL server on both of them. The OS is RHEL 4 with
the default kernel 2.6.9-5.ELsmp. These days there are lots of error
message comming out in /var/log/message and dmesg.

KERNEL: assertion (tp->copied_seq == tp->rcv_nxt || (flags & (MSG_PEEK |
MSG_TRUNC))) failed at net/ipv4/tcp.c (1348)

When it appeared, the network of Marvell card has been broken. It
connected but accessable.
We have installed the driver of the Marvell card manully with the driver
"Driver version: 8.30.2.3 (Dec-14-2005)".

I have digged in google for a long time. But unluckly, i haven't got the
sulotion.

Did i need a kernel upgrade or driver upgrade or anything else?

Every response is apperciated.

Wang.
