NMI errors with 2.6.13 (and 2.6.12.x)

[Dimitri Puzin]

Hello,

I've got a Tyan S5112 (Intel E7210 Chipset) and 2x256 MB ECC RAM. The
CPU is a P-IV 3.0GHz HT. I run the current vanilla kernel on
Debian/Sarge. The config is attached. The kernel is booted with
nmi_watchdog=1. That box logs random oopses [0] to the syslog but
doesn't freeze. I've already tried different configs with and without
ACPI, SMP, HT etc, but no useful results. When ran without nmi_watchdog
the /proc/interrupts gets filled with ERR interrupts. The call trace is
every time different. The same appeared with 2.6.12.x series when I was
figuring what's running bad. The current release shows the same. Could
anyone give some advice on that?

Kind regards
