Under load, sky2 causes the system to hang. The only output on the console is the following: [55022.353219] NETDEV WATCHDOG: eth0: transmit timed out [55022.358356] sky2 eth0: tx timeout [55022.361753] sky2 status report lost? The problem exists in all kernels I've tested: 2.6.17 through 2.6.19-rc6-mm2. Every now and again the network device will crash, but won't take the system down with it, and I'm able to recover with rmmod sky2 / modprobe sky2. If the system does crash, after a reset, sky2 does not come up properly, but unloading and reloading the module will recover it. There is no appreciable difference with receive checksums disabled.

I am only using one of the ethernet ports, the other is disabled in the BIOS.
