Hi,
I'm experiencing heavy TX Unit hangs in a TYAN Toledo i3210W/i3200R S5211 with
both onboard e1000 NICs since I bought the board in May 2008.
These hangs therefore occur in several kernel versions now (2.6.31.*,
2.6.30.*, 2.6.29.*).
I replaced the unmanaged switch with a managed one without any improvement.
Because of the new switch's trunking capability it runs in bonding mode now
but the error also occurs without bonding on both interfaces.
It doesn't occur with older 66MHz PCI based e1000 cards.
I'm running a Gentoo box with a vanilla kernel.
Kernel cfg can be provided just like any more information which could be
helpful.
Cheers,
Vasco
