So I built a kernel (GENERIC) with debugging symbols and DDB option. Now I'd like to provide usefull info about the following crashes: 1. booting from degraded RAID1 with HPT372 (machine crashes and I see db>) 2. crash when unquirked UMASS is unpluged 3. crash when /stand/sysinstall is called after some uptime 4. machine hangs when LPT is removed in BIOS and ACPI enabled (no crash, I think I have to enter DDB with ctrl-alt-esc?) I read the FAQ (18.13. How can I make the most of the data I see when my kernel panics?) but I think this isn't applicable to my crash when the machine crashes before rc.conf can be read. And I really don't understand what he's talking about :( but perhaps I can help. Please tell me if I should do something like "trace" and write it down or something like that. Thanks, -Harry
