Hi everybody

My network card (pci-express marvell yukon 88E8053) use the new sky2 network driver.
The driver works fine when the load is not so huge but when the traffic
increases (ftp download...), the card hangs.

I just need to stop and restart the network service to use the network card again.

here is the output of dmesg when the card freezes

sky2 eth1: tx timeout
sky2 eth1: transmit ring 397 .. 356 report=399 done 399
sky2 status report lost?

Have you got an idea about the problem ?

seb.

Same problem as earlier bug.
Most likely due to transmit flow control (see patch in other bug report)
