Thanks for the quick response. Indeed, the patch makes the alignment faults go away. But the 'device timeout' messages coming from cpsw(4) remain.
To elaborate a bit, I set up three terminals pinging 192.168.123.201, 192.168.123.202, and 192.168.123.222 (the shared IP). After ~1min I get no answers from 192.168.123.201 and 192.168.123.201 (although the times differ). For a few minutes the hosts remain unreachable. dmesg output looks like carp0: state transition: BACKUP -> MASTER carp0: state transition: MASTER -> BACKUP carp0: state transition: BACKUP -> MASTER cpsw0: device timeout carp0: state transition: MASTER -> BACKUP carp0: state transition: BACKUP -> MASTER cpsw0: device timeout ... This bug seems unrelated to the alignment faults issue. I would investigate given some pointers in the right direction. If this is under the purview of cpsw(4), would it be advisable to submit a new bug report?
