Hello all,
as I already reported exactly one year ago I am still experiencing Tx Unit
hangs on two 82573 NICs on a TYAN Toledo i3210W S5211 (4GB RAM) running Gentoo
64 Bit.
The box is running since May 2008 and has shown continuous Tx Unit hangs since
then. The vanilla kernel was updated quarterly from 2.6.29.x upon install up
to 2.6.36.1 currently.
I also replaced the unmanaged switch with a managed one but without any
improvement.
Box was freshly rebootet.
Sometimes eth0 hangs, sometimes eth1 does.

Kernel cfg and more infos available upon request.
Bonding is properly configured and trunking enabled on the switch.
It also happens without bonding.
Any help appreciated.
