Subjectrtl8139 nic dies with load (2.4.10, kt266)
Hi,

my box got 2 rtl8139 nics (longshine iirc), eth0 connected to localnet
and eth1 for adsl (pppoe).
since i upgraded the hardware to via kt266 + athlon c 1.4 and kernel
to 2.4.9 all network activity dies when i copy big files over
localnet. with old hx chipset, cyrix 200mhz cpu and redhat 2.4.3
kernel i didn't have these problems.
no matter if ftp or smb, when transferring files over eth0 to a win2k
pc (3com nic), after some seconds or mbytes transfer, suddenly all
network activity on eth0 dies. the adsl connection over eth1 remains
alive.
after /etc/rc.d/init.d/network restart all is fine again (rebooting
the win2k pc doesn't help ;). and it remains so until i make significant
traffic. even while watching an divx files over a samba share, the nic
died after 45 minutes of continuous watching.

meanwhile i updated to 2.4.10 but it does not fix it. also 2.4.9-ac16
shows the same behaviour.
i found no messages in /var/log/* or on console telling errors.
below some hw-specs (rtl8139-diag output at the end).
i'd be glad if i could help with more information or trying patches etc.

good luck,
Oliver Seemann

ps: i'm not subscribed, please reply directly. thx
