I've been using RAIDframe on NetBSD 1.5.2 to stripe eight fibre
channel disks.  This has been working OK, modulo some soft errors
which didn't seem to actually cause any problems.

Yesterday, I switched to a NetBSD-1.5ZA kernel, using yesterday's
sources, in order to solve another problem which I believe to be
unrelated.  Overnight, the machine became unresponsive, with this
in syslog:

Feb 27 03:27:27 reader1 /netbsd: raid1: IO Error.  Marking /dev/sd4a as failed.
Feb 27 03:27:27 reader1 /netbsd: raid1: node (R  ) returned fail,

Feb 27 03:47:25 reader1 /netbsd: Failed to write RAID component info!
Feb 27 03:53:22 reader1 /netbsd: sd1(isp0:0:57:0): adapter resource shortage

I'm wondering what the source of the IO errors from RAIDframe can
be, when the kernel is not reporting disk errors.

dmesg output from the machine in question is attached.
