On my sky2 platform [1], I'm still seeing lockups after some time [2]
with 2.6.21 (including all the -rc kernels). I've found that 'ethtool
-K lan0 rx off' seems to workaround the problem - I'm running with 9k
jumbo frames, but I find the problem with 1500 byte frames also.
Perhaps you need to blacklist this hardware as having RX offload problems too?
Thanks,
Dan
