Unfortunately, my machine now panics. I don't know the cause of the 1st panic as it rapidly scolls off of the console. It eventually dies with a double-fault and hangs. I can boot it into "-s" single-user state, and it launchs a shell, but as soon as I type "fsck -p", it's gone bye-bye.
The aic7xxx.c from the night before actually works for me, but during probing it generates a lot of errors trying to look for LUNs that don't exist. Perhaps the Sony-926S CD-R drive needs a quirk of some sort? (The UMAX doesn't have this problem which it did with the pre-CAM code.)
I've attached my working dmesg.out file from the earlier aic7xxx.c file. I get lots of timeouts and resets, but once it's finished probing, things seem to be running just fine.
(Softupdates is enabled on all volumes too, and with the latest patches, seems to work just fine. It's survived 8 make -j8 buildworld so far while using X and in general beating the crap out of it. I managed to get the system load above 9, which is a first for me.)
