I tried this, but when the box froze, the keyboard was completely unresponsive, no numlock, nothing. The serial console is similarly unresponsive. I have all the debugging options that are on in the default GENERIC from -CURRENT which include DDB. I have also checked out the section in the handbook on serial consoles and enabled the option BREAK_TO_DEBUGGER as suggested there. Break does not get a response either. It may be worth noting that I can get a freeze condition on any large operation regardless of the -j setting for make. As an additional note, dmesg output for the problematic kernel can be seen at http://archeron.wavefire.com/~wade/dmesg.arch.txt . This is not localized to a keyboard. Screen save freezes, remote sessions lock and machine pings as if dead. Any other avenues I can follow to resolve this or find the problematic code/hardware? thanx. -Wade Klaver To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
