I couldn't figure out how to do that using the Open Firmware boot loader --= - it doesn't understand sysctl, AFAICT. I tried the -d kernel switch but it did= n't change anything. This machine lacks a serial port, which makes traditional kernel debugging difficult. I noticed that its Open Firmware version does support telnet connections, though. Is there a way to use that facility for a kernel debug console? --=20 You are receiving this mail because: You are the assignee for the bug.=
