index | next in thread | raw e-mail
Over the past couple of weeks, I've been experiencing a problem where
-STABLE after Oct 28th would hang on booting. The only change that
appeared to be on the 29th was the amr driver changes that Eric committed,
and he suggested upgrading the firmware on my MegaRAID controller to
'correct' the issue.
Last night, Rackspace performed that upgrade for us, and powered up using
the same kernel (RELENG_4_7) we had installed ... it hung on reboot.
They could boot off of the GENERIC kernel that I still had on that
machine, but not the kernel that I had running several hours previous ...
after playing with the kernel config for a period of time, I finally
figured out that as long as I didn't enable SMP, the kernel would boot.
Not good, but better then nothing ...
Today, after getting some rest, I dove back into things again, finally
thinking to setup /boot.config to enable -v on boot, figuring that was hte
only way I was going to more detailed information ...
After looking through /var/run/dmesg.boot after trying to boot an SMP
kernel, I noticed that the kernel isn't detecting the second CPU in the
machine:
IOAPIC #0 intpin 2 -> irq 0
Programming 16 pins in IOAPIC #1
SMP: CPU0 apic_initialize():
lint0: 0x00000700 lint1: 0x00010400 TPR: 0x00000010 SVR: 0x000001ff

pnpbios: Found PnP BIOS data at 0xc00f4c50
pnpbios: Entry = f0000:3954 Rev = 1.0
Other BIOS signatures found:
ACPI: 00000000
whereas my other server, same motherboard and BIOS level, shows:
FreeBSD/SMP: Multiprocessor motherboard
cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000
cpu1 (AP): apic id: 1, version: 0x00040011, at 0xfee00000
io0 (APIC): apic id: 4, version: 0x000f0011, at 0xfec00000
io1 (APIC): apic id: 5, version: 0x000f0011, at 0xfec01000
Now, I've had Rackspace check to make sure that the second CPU is, in
fact, in the machine, and they went to the extent of swap out the CPUs and
put new ones in ... the CPUs are detected by the BIOs itself, its only
once it gets to the OS level that it seems to "lose" the second CPU ...
The kernel config I'm trying to boot is quite basic, and included at the
bottom of this, as well as the output of mptable -verbose:
What would cause a CPU to "disappear" as far as the operating system is
concerned? And how could a firmware upgrade (and/or driver upgrade) cause
this? This is a totally new one for me, and I haven't got a clue what
direction to go at next ...
