Hi,

With reference to the following thread :
http://groups.google.com/group/mailing.freebsd.smp/browse_thread/thread/bd45afab721e1a85/f66c8476272952af?lnk=st&q=%2Bfreebsd+%2B%22failed!%22+%2Bpanic&rnum=80#f66c8476272952af

I am seeing the same issue on an Intel SE7501CW2 dual Xeon machine. 6.0 as
well as -current exhibits the same behaviour. Various postings to the
above thread suggests that this may be due to the APIC ID that the BIOS
claims is assigned to the CPU not being the actual APIC ID assigned to the
CPU. Does anyone have any new information on this issue? If the subsequent
panic succeeded in rebooting the machine this would not be a big issue for
me but unfortunately the machine hangs after pressing 'y' to the "panic
[y/n]" prompt. Is there a way in which to initiate a hard reset in
software?

regards,
jacques
