[BUG]: RT8139 Too much work at interrupt, IntrStatus=....

[Dennis Schoen]

Hi all,

yesterday I upgraded a firewall/router of a *busy* customer site
from version 2.4.7 -> 2.4.17. Only 1-2 seconds after the reboot the
network card to the DMZ stopped working. I noticed this messages in
/var/log/messages:

Jan  8 17:07:45 liquice kernel: 8139too: rx stop wait too long
Jan  8 17:07:46 liquice kernel: eth1: Too much work at interrupt, IntrStatus=0x0050.

Jan  8 17:08:09 liquice kernel: NETDEV WATCHDOG: eth1: transmit timed out
Jan  8 17:08:09 liquice kernel: eth1: Setting 100mbps half-duplex based on auto-negotiated partner ability ffff.

after a reboot the same problem occured.

Switching back to v2.4.7 solved the problem so I don't think that
it's a hardware issue.

So has anybody an idea whats happening here? Hardware info below. Let me know if you need any additional info.

Thanks
