Hi,

I have an ALR Revolution Q-SMP board with four P133 processors
on it.
I tried to run 2.1.97+IO-Apic patch, but it still won't work :-(

I can run the 2.1.97 kernel fine with UniProcessor kernel.
SMP_kernel compiles OK, but at booting it always comes to :

CPU0: Intel Pentium 75+ stepping 0b
Calibrating APIC timer
..... CPU Clock speed is 133.3200 Mhz
..... APIC bus clock speed is 533.3113 Mhz.
Booting processor 1 eip2000 : Not responding
Booting processor 2 eip2000 : Not responding
Booting processor 3 eip2000 : Not responding

The system then tries to boot further and finally hangs at :

Kernel panic : IO-APIC + timer doesn't work !

Any ideas ?

Greetings,
Wim Binneveld
