You did get them at home too? (with the same (type of) hardware?)

10ms is a very long time. Normally the hardware resets a lot faster than
that, and when it doesn't I suspect it is in some really bad state.

You are not the first to report this. And it is a message that could be
caused by a lot of things, I guess.


But I have finally managed to get these timeouts to happen on my VT6102
too (using an evil combination of running a remote Internet Explorer over
VNC). I have planned to examine it, but I probably won't get around to
that for at least a couple of weeks.

Some ideas you could try:
+ The via-rhine driver at
http://www.scyld.com/network/ethercard.html
(the one in the kernel is almost the same as this one)
+ Move the card to another slot (remove/re-arrange other cards in the box)
+ Since it appears to be load related, perhaps it can be hidden by slowing
things down (eg add a small udelay() to via_rhine_start_tx)

(or you could try to figure out what the driver is doing when these
things happen.)
