Description dustinh 2001-01-10 04:30:01 UTC
SMP kernel hangs on boot on a Compaq DL360 (dual PIII-800, 512MB RAM).  Patch from PR 19338 was reported to have fixed thise problem with SMP and the DL360 and was applied to the stable branch on 12/8/2000 by peter@freebsd.org.  The output below does show that the workaround code from that patch is being executed (/usr/src/sys/i386/i386/mp_machdep.c).

Boot looks like this:

FreeBSD 4.2-STABLE #2: Wed Jan 10 03:33:18 GMT 2001

APIC_IO: MP table broken: 8259->APIC entry missing!
Changing APIC ID for IO APIC #0 from 0 to 8 on chip
Programming 35 pins in IOAPIC #0
IOAPIC #0 intpin 2 -> irq 0
IOAPIC #0 intpin 24 -> irq 2

Note that the system does work correctly in 4.2-STABLE with a non-SMP kernel.

How-To-Repeat: Update system from 4.2-RELEASE to 4.2-STABLE as of January 8th.  Build a GENERIC SMP kernel by uncommenting the SMP and APIC_IO options and removing all cpu lines except I686_CPU.
