It works for me on 10.0. Do you have debug.kdb.break_to_debugger=1 and hw.syscons.kbd_debug=1 (if you're using syscons)? -- Peter Jeremy pgpRWEUgfMxEM.pgp Description: PGP signature

You might need to modify and load a keymap, specifying debug as the action for the appropriate combination of keys.

keyboard break to debugger broken?
So, I recently tried to break into the debugger w/ the various key sequences that I know about, and none of them worked... I've tried CTRL-ESC, ALT-ESC, CTRL-ALT-ESC, CTRL-PRTSCR, ALT-PRTSCR and CTRL-ALT-PRTSCR, and many other different ones... I've verified that I can sysctl debug.kdb.enter=1 to enter the debugger, and the CTRL-ALT-PAUSE works to suspend the machine, and CTRL-ALT-DEL works to reboot... Does anyone know if this works? Thanks for the pointers... btw, I'm having trouble on 9stable too. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
