my server with Linux 2.0.pre37-5 occasionally gets very slow on eth0.
The problem can be seen in the following ping output:
64 bytes from 172.30.2.8: icmp_seq=31 ttl=64 time=518.4 ms
64 bytes from 172.30.2.8: icmp_seq=33 ttl=64 time=6.2 ms
64 bytes from 172.30.2.8: icmp_seq=32 ttl=64 time=1007.1 ms

64 bytes from 172.30.2.8: icmp_seq=35 ttl=64 time=628.2 ms
I didn't observe this problem with 2.0.36 (yet). Maybe this is because
I installed a second network card about the same time.
Taking the interface down an up again helps but even after that it
doesn't work well:

BTW the VIA Rhine driver seems to perform rather badly. Any ideas?
And why is the VIA Rhine message duplicated? And why does it detect
a VT3043 when my the chip on my card is a VT86C100A?
Thanks,
