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

Hi all.

I have a strange problems with the network card.
One time I have got a kernel panic.
You could see screenshot from IPKVM here: http://paix.org.ua/tmp/panik_260509.jpg

Sometimes under high network load my server become unavailable, but trough IPKVM server works fine, and after
Code:
service network restart
netcard start work again.

Very often under high network load too my server become pings with a very long time.
Code:
64 bytes from xxx.xxx: icmp_seq=71 ttl=56 time=2218 ms
64 bytes from xxx.xxx: icmp_seq=72 ttl=56 time=2208 ms
64 bytes from xxx.xxx: icmp_seq=74 ttl=56 time=1047 ms
Server connected by 100mbit link, and I ping it from neighbour machine.
And after
Code:
service network restart
server come in to normal behavior.

I am running openvz kernel, which is based on the current RHEL5 kernel.

Code:
#uname -a
