No further errors in dmesg.
This is 2.6.25.4-xfspatch-dirty - it has the patch for xfs on partitioned raid
arrays. It also has the external lirc module loaded.
The system was in the process of rsync-restoring 1Tb of data to a new 5x1Tb
raid5 that was running degraded. The filesystem is xfs.
The rsync ended like this:
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(541)
[generator=3.0.2]
rsync error: received SIGUSR1 (code 19) at main.c(1295) [receiver=3.0.2]
which may be linked but I don't have timestamps for that.
