This is a multi-part message in MIME format. --------------090403080900000406070508 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit I had previously posted something very similar to -current with BETA2, but received no replies. Also the SMP factor might make this more appropriate here :-) Tyan S2510 dual PIII 6.0-BETA3 (dmesg attached for case with USB disabled): kernel(SMP) + bios(USB disabled) -> hang at reboot whereas kernel(SMP) + bios(USB) -> reboot ok As I am still a kernel debugger newbie (and because the hang state was unresponsive to keyboard break), I added a few printfs instead to pin down where the hang was. It appears to be in: src/sys/i386/i386/vm_machdep.c:cpu_reset_real() specifically: #if !defined(BROKEN_KEYBOARD_RESET) printf("cpu_reset_real: case !BROKEN_KEYBOARD_RESET \n"); /* <==== HANGS AFTER DISPLAYING ==== */ DELAY(1000000); /* * Attempt to do a CPU reset via the keyboard controller, * do not turn off GateA20, as any machine that fails * to do the reset here would then end up in no man's land. */ outb(IO_KBD + 4, 0xFE); /* <==== DEDUCE HANG HERE ==== */ DELAY(500000); /* wait 0.5 sec to see if that did it */ printf("Keyboard reset did not work, attempting CPU shutdown\n"); DELAY(1000000); /* wait 1 sec for printf to complete */ #endif (I have spattered the nice clean source with printf's and DELAY's... but you get the idea). So outb(IO_KBD + 4, 0xFE) *looks* like the culprit. So anybody have any ideas why *SMP* is triggering this? Or why it is happening anyway? cheers Mark --------------090403080900000406070508 Content-Type: text/plain; name="dmesg.nousb" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="dmesg.nousb" Copyright (c) 1992-2005 The FreeBSD Project.
