Hello,

For the last few days I've had some spontaneous reboots and a large
volume of scary looking messages from the isp driver, which I don't know
how to interpret:

http://people.freebsd.org/~ivoras/stuff/messages.isp_problem.txt

The only think that's changed is that I've modified some volume-host
mappings in the SAN storage device (HP MSA 2000, on the 20th), but not
for this host or for any volumes this host has access to.

The volume of messages is high because I have

hint.isp.0.debug=3D0x30f
hint.isp.1.debug=3D0x30f

in my loader.conf from some earlier debugging session, but the reboots
concern me. Can someone interpret the log?

Another host connected to the same SAN doesn't show such errors, but
it's also much more lightly loaded. The only messages on this other host
are:

Aug 23 11:36:56 freddy kernel: isp0: Chan 0 PLOGX PortID 0x010200 to
N-Port handle 0x8: already logged in with N-Port handle 0x2
Aug 23 11:36:58 freddy kernel: isp1: Chan 0 PLOGX PortID 0x010200 to
N-Port handle 0x8: already logged in with N-Port handle 0x2
