Zahadny problem se sitovkou

[Michal Ludvig]

Zdravim,
uz se tady dost dlouho potykam s nasledujicim problemem:
mam router se dvema sitovkama 
1) RealTek RTL-8029 - ta chodi v pohode
2) 3c905B - s tou je problem.
Kdyz ji naifconfiguju, nastavim routovani a chci si nekam pinknout, tak
nez mi prijde odpoved, trva to strasnou dobu - leckdy prijde prvni opdoved
az na 14tej, 15tej paket. Kdyz na tom interfacu tcpdumpuju, hazi mi to mj.
nasledujici:

13:46:53.470285 truncated-ip - 38 bytes missing!10.0.0.6 > 10.0.0.1: icmp: echo

13:47:06.100285 truncated-ip - 38 bytes missing!10.0.0.6 > 10.0.0.1: icmp: echo

13:47:06.650285 truncated-ip - 38 bytes missing!10.0.0.6 > 10.0.0.1: icmp: echo

Taky kdyz uz se to rozpinga, sem-tam se stane:

64 bytes from 10.0.0.3: icmp_seq=316 ttl=128 time=3.7 ms
64 bytes from 10.0.0.3: icmp_seq=317 ttl=128 time=3.8 ms
64 bytes from 10.0.0.3: icmp_seq=276 ttl=128 time=41869.0 ms (DUP!)
64 bytes from 10.0.0.3: icmp_seq=318 ttl=128 time=3.8 ms
64 bytes from 10.0.0.3: icmp_seq=319 ttl=128 time=3.8 ms

Samozrejme veci jako telnet/ssh nechodi vubec. Nevite, kde je chyba?
Mam jadro 2.0.36, ovladac 3c59x v0.99H (nejnovejsi).
