Re: [PATCH] Re: Catching NForce2 lockup with NMI watchdog - found

[Vladimir Grebinskiy <v_lkm@list.ru>]

I hope you nailed the problem! I applied the "timer APIC-IO-edge" change 
and "athcool off" patch and the box seemed to be working with APIC/LAPIC 
(for the first time) !!! The board is the Leadtek K7nCR18G-Pro, BIOS 
9/30/2003, kernel 2.6.0-test11 and Debian/Sid (all debug turned on, 
preempt off).

The box used to lock up in seconds when running "md5sum bigfile" unless 
booted with "noapic nolapic". Now it survived parallel read from two 
drives + "ping -f router" + glxgears (with nvidia video driver). I'll 
keep testing it for a while.
