The 300 TX4 model is causing transient errors for several people,
and we don't yet know why. In your case, port_status 0x00001000
means that "host bus is busy more than 256 clock cycles for every
ATA I/O transfer" (quoting the docs). Basically it's a timeout.
I'm running vanilla 2.6.22-rc7 here, getting a similar error.

Identical card to the one otto posted. How common is this? I
wouldn't notice if it wasn't logged - I don't notice the blip in disk
access.
