SubjectProblems with the new "smp-calibration" routines
Hello,
I have some problems with the new linux-kernel (2.1.86, 2.1.87) concerning
their new "smp-calibration" at the beginning of the boot-process (i don't
have a better word, because i don't know what happens here ;)

I have an Asus P65UP5 motherboard with a C-P55T2D pentium-CPU-card
and two P166MMX Intel CPU's. The CPU's are overclocked, they run at 200MHz
For the last 6 month (using 2.0.x, 2.1.5x) I have no problems, the machine
runs very stable ! But I notice something strange: One CPU seems to be slower
than the other, because of different bogomips. Here my /proc/cpuinfo
under 2.0.33:

processor : 0
cpu : 586
model : 4
vendor_id : GenuineIntel
stepping : 3
fdiv_bug : no
hlt_bug : no
f00f_bug : yes
fpu : yes
fpu_exception : yes
cpuid : yes
wp : yes
flags : fpu vme de pse tsc msr mce cx8 apic mmx
bogomips : 398.13
^^^^^^
processor : 1
cpu : 586
model : 4
vendor_id : GenuineIntel
stepping : 3
fdiv_bug : no
hlt_bug : no
f00f_bug : yes
fpu : yes
fpu_exception : yes
cpuid : yes
wp : yes
flags : fpu vme de pse tsc msr mce cx8 apic mmx
bogomips : 331.78
^^^^^^
Last week I've tried 2.1.86 (and today 2.1.87) but I can't boot the kernel,
it hangs after the new "smp-calibration" with the following error message:
...
16 000 00 1 0 0 0 0 0 0 00
17 000 00 1 0 0 0 0 0 0 00
Starting Kswapd v 1.23
parport 0: PC-style at 0x278 [SPP,PS2,EPP]
Ugh at c010a4a4
divide error: 0000
CPU: 0
EIP: 0010: [<c010f0de>]
EFLAGS: 00010097
...
Running the CPU's at "normal" speed (166Mhz), everything works fine, but I
don't want to do without the additional 34Mhz ;)

Any hints ?
