Default Re: CentOS 5.2 network bugs, kernel panic (forcedeth, MCP67)

Recently I have got too panics, when I tested the network by iperf.

kernel booted with
Code:
irqpoll nousb noapic

kernel booted with
Code:
nousb noapic
and

Code:
alias eth0 forcedeth
options forcedeth optimization_mode=1
http://paix.org.ua/tmp/panic2_190609.jpg

Also there is one interesting oops in log/messages:
Code:
kernel: skb_over_panic: text:ffffffff881bf46f len:15398 put:15398 head:ffff8100a25c5800 data:ffff8100a25c5810 tail:ffff8100a25c9436 end:ffff8100a25c5e80 dev:eth0
kernel: ----------- [cut here ] --------- [please bite here ] ---------
kernel: Kernel BUG at net/core/skbuff.c:96
Also I have a kernel booted with crashkernel=128M@16M option, and I have kdump running, but unfortunately there are no any saved core. I couldn't reboot server via ipkvm too, so I've requested a support to hardware reboot the server.

dmesg:
