Locked up tight. Booting the UNI kernel works fine. > I can't get into DDB or anything. Since there are 2 unknowns here, the ZX6000, and the DPT patches, you need to seperate them. Idealy, you want to boot with a completely original SMP-generic and 'standard' scsi or ide card/disk. We need the output of "mptable -dmesg > file" run from the UP kernel. Start the UP kernel with the verbose (-v) switch, then run mptable as soon as logged in. I'm not sure about 8/20, it works here, but it has some not well tested stuff in it. From the web page: The 970815-SNAP is considered the most recent 'stable' snapshot. Past this date experimental work on lock pushdown is in progress. If you have NOT used FreeBSD SMP on your hardware before, start with the 970815 SNAP. After verifying that SMP works on your system you are encouraged to cvsup to the latest code and help exercise the lock changes. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
