I noticed this while poking around:
[notting@wierzbowski: ~]$ cat /proc/unalignedinfo
Last userland trap : Last kernel trap : kernel unaligned access to
Kernel trap count : 48
ip decodes to (if I'm reading it right) tcp_parse_options.
2.4.9-7.2smp. Will install -11 and see if it persists.
THis is not a bug; there's some places in the tcp/ip stack that in rare
occasions will do an unaligned access. "fixing" those is not an option as that
would slow down very hot paths.
