FreeBSD 5.X on Siemens Nixdorf Primergy bombs

[Georg Schwarz]

Hi,

I have a Siemens Nixdorf Primergy Dual-Pentium-I machine. It has a
Siemens (or SNI) D823 motherboard with an Intel Corp. 82434LX
[Mercury/Neptune] chipset. It runs nicely with FreeBSD 4.X:

BTW, the CPUs really are 133 MHz; I do not know whxy it gets wrong the
frequency (it varies with every startup).

Now when I boot FreeBSD 5.2.1 (or similarly install FreeBSD 5.0 or 5.1
with an SMP Kernel) it bombs on booting:


...
mpx0: [FAST]
mpx0: <math processor> on motherboard
mpx0: INT 16 interface
pcibios: BIOS version 2.00


Failed trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address   = 0x22
fault code              = supervisor read, page not present
...

and a few other things which I will write from the screen only when
sameone says they are really of help.
Fas anyone have an idea what might cause that crash?


PS: I am running a second PC of that type with Linux. With Linux 2.4.X.
With Linux 2.4.21 and 2.4.22 SMP did not work there due to some chages
in the Kernel compared to previous (e.g. 2.4.20) version. With 2.4.23
that has been fixed. I am mentioning this here because it might help
identifying the problem.
