you can try adding kernel arguments like: noapic, nolapic, noacpi, irqpoll (not all at once)

you can try changing the kernel config. irq polling styles (at-apic vs acpi is it?) cpu types (i386 vs Athlon), scheduler types (cfq vs this vs that)

if you find out how to debug a frozen kernel (ie, doesnt even get a chance to print a backtrace) let us know. ive been tryin out ingo's kernel every 6 month or so for the past couple of years on a few differet amd64 rigs using the above techniques. so far it always blackscreens/reboots right after grub, freezes during boot, or freezes anywhere from 3 to 20 minutes after booting regardless of load. i dont want to say the above techniques are a total waste of time, as they do tend to change when it freezes from eg, right after grub, to later on, etc. so theyre doing something..

 Is anyone successfully running a realtime kernel on a similarly old
