just found my on hand ck804, and mcp55 based AMD servers:
nmi_watchdog=1 doesn't work
but nmi_watchdog=2 does work
=1, it say: IOAPIC 8259A virtual wire mode...
Did nmi_watchdog=1 work on any other amd64 platform?

I think I used it, but I don't remember when. Will try tomorrow.

any update?
non amd64 based system works with that. (amd8111, ck804, mcp55)
or 8259 virtual wired mode to local apic LVT0 never work?

I booted 2.6.23 on a HP NX6325 laptop with nmi_watchdog=1, and dmesg says,
...
..MP-BIOS bug: 8254 timer not connected to IO-APIC
timer doesn't work through the IO-APIC - disabling NMI Watchdog!
nmi_watchdog remains to be 0, as I read by a simple kernel module.
