Mainboard with Serverworks HE Chipset

Mainboard with Serverworks HE Chipset

[Matthias Schniedermeyer]

#include <hallo.h>



I got a "Tyan Thunder HE-SL"-Mainboard today, which has a "Severworks
ServerSet III HE"-Chipset. (2xPIII 933, 2x512MB PC133 ECC-Registered
SDRAM)

And i have one problem and one question.

First the question. I have an uptime of phenomenal 29minutes and "cat
/proc/interrupts" tells me this

NMI:     175819     175819
LOC:     175829     175828

Should i be worried? Or can i ignore it. With my former Mainboard NMI was
(AFAIR) always 0.

Now my problem.

The Graphic-Card is a Geforce 2, Xfree is 4.02 (compiled under 2.2.17).

When i start X, everything is fine. When i go back to text-console and
wait "some time" and then switch back to X the computer locks solid and i
have to press the Big-Red Button. (Switching back to X after a "short"
periode of time, at the text-console, works "normaly")

If anyone needs more information, i will happily provide them.

	My ASUS P2B-DS with intel 440BX/ZX chipset shows the same.

	As far as I can see, that means SMP with APICs.
	"LOC" is "Local APIC", "NMI" is perhaps "Remote APIC",
	or inter-processor APIC call, or some such.

	I have same card, but haven't tried to do that kind of switching..
	.. at least not recently.

	You don't mention which kernel you are running, and what userspace
	package.

I knew i forgot important details. :-)

You could try booting with 'nmi_watchdog=0' and see what happens.
What you describe sounds like the problem I have seen on a few boxes, and
disabling the NMI watchdog makes the huge numbers of NMIs and the system
hang go away. Still unclear why this is happening.

Thanks,
this seems to confirm my suspicion that there's some incompatibility between
the NMI watchdog code and the Serverworks chipset. Still trying to find out
exactly what's wrong...
