Could both of you please send details on the configuration: 1) CPU class (eg. P5/133) 2) controller chip (810 or 825) 3) disk drives connected 4) type of hang (does the SDMS BIOS probe complete ?) Since 1-3) is reported in the boot messages, I'd like to receive a verbose boot log. Regarding the kernel dump: It used to work at a time, and I'm not sure what makes it fail. There was some way to obtain a kernel core with DDB at no risk of data corruption on the disk (which I couldn't take !), but I don't remember any details. I'll build a kernel with the debugger and will try to test the dump feature over the next few days. (Please allow 10 days for me to get it fixed ...) Regards, STefan
