2.6.28 crashed in tcp_recvmsg.

Quoted 3 lines

Latest working kernel version: none
Earliest failing kernel version: 2.6.26.5

And apparently 2.6.26.5 does the same thing?

I would be suspecting a hardware failure here. Can we have more details please? Some additional oops traces from this or earlier kenrels might help.

Is the failure seen on other machines, or just this one?

Does it help if you disable CONFIG_NET_DMA?
