Immediately after the Giant Lock message (even in verbose logging mode) the system freezes hard (i.e. caps lock fails to toggle the keyboard LED). I have tried some desperate measured, such as reducing ram to 1gb and running a single processor, with the same results. Interestingly, neither Debian nor Red Hat can find the drives, but they don't crash. I have flashed the BIOS on the MegaRaid to the latest available from the HP website. That made no change to the result. I am about to disable IDE and try to install from floppy. It's the last, best desperate move I can make.
