Hello,
I installed 4.8-RELEASE a few weeks ago, and since I let
the effort sit stagnant for a while I decided to do the
cvsup/buildworld/buildkernel/installkernel/installworld/mergemaster/MAKEDEV
steps to get current.
Went fine, rebooted, then noticed that just one CPU was recognized:
FreeBSD 4.8-STABLE #0: Thu Jun 19 17:05:20 PDT 2003
mark@lah-210.mainstreet.net:/usr/src/sys/compile/MDK
FreeBSD/SMP: Multiprocessor motherboard
cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000
io0 (APIC): apic id: 1, version: 0x00170011, at 0xfec00000
I confirmed my kernel config was OK, rebuilt it, rebooted
and got the same result. I also looked at 'mptable' and 'top'
to make sure.
I boot off my backup disk and I get:
FreeBSD 4.8-RELEASE #0: Thu May 29 14:48:37 PDT 2003
mark@lah-210.mainstreet.net:/usr/src/sys/compile/MDK
FreeBSD/SMP: Multiprocessor motherboard
cpu0 (BSP): apic id: 1, version: 0x00040011, at 0xfee00000
cpu1 (AP): apic id: 0, version: 0x00040011, at 0xfee00000
io0 (APIC): apic id: 2, version: 0x00170011, at 0xfec00000
So, there it is. Both cpu (also present in mptable and top).
I confirmed that the kernel config is identical.
Any idea what I screwed up on the way to 4.8-STABLE that
lost me the SMP?
Thanks,
-mark
