I have seen the following problem, first when booting from the
4.7-RELEASE floppies.  I also saw it after successfully installing
4.6.2-RELEASE, while upgrading to the most recent 4.8-STABLE (after
make installkernel, during the reboot into single-user):

<snip>

isp0: cannot find handle 0xa (status 0x6)

</snip>

The same portion of a normal dmesg (from a 4.6.2-RELEASE kernel) looks
like:

<snip>
Waiting 15 seconds for SCSI devices to settle

da1: 4091MB (8380080 512 byte sectors: 255H 63S/T 521C)
</snip>

With this problem, none of the SCSI disks are detected correctly.

Does anyone know of changes related to the isp driver between
4.6.2-RELEASE and 4.7-RELEASE that may have caused this problem?

Thanks,

Jim
