This has me puzzled:
I have a 2 cpu S2515 that has had SMP added to the kernel - however upon
reboot the 2nd cpu is not detected (It is detected by the BIOS BTW). I
see the following in the verbose dmesg:
APIC: Could not find any APICs.
I am guessing that it is turned off in the BIOS (???), if so, I've no
idea where it is (AMIBIOS is my least favorite...).
I have enclosed a verbose dmesg and my kernel differences from GENERIC
plus the (non-existent) output from mptable.
Any ideas appreciated.
You're going to need to fiddle with the BIOS until mptable(8) finds a valid MP
Table. The kernel relies on the MP Table to enumerate CPUs and route
interrupts. You can also try enabling ACPI if your machine supports ACPI.
Ok - will do. I
One other point, the cpus are both PIII SL52R (1000/256/133/1.75V), but
they don't appear to be a matched pair (one is made in Malay, the other
somewhere else - the heatsink is over it...) would this matter?
Another possibility is that one of the cpus is faulty - should mptable
show anything if one cpu is not "really" going (or for that matter if I
remove one of 'em)?
Thanks for the advise
Mark
