Apart from the fact that both machines are about the
same age, they don't
seem to have much in common. However, both fail to boot at the same
point.
NET: Registered protocol family 2
Then it just stops. I've tried many different kernel versions (2.6.17-rt8,
2.6.17-rt5, even as far back as 2.6.13-rt14), to no avail. I also tried
turning ACPI and APIC on/off, which didn't help either. Now I'm at a
loss... The same kernels boot just fine on a more recent machine.
What else can I try, or how do I find out where exactly (and why) it
hangs?
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
machine?
Thanks,
Dominic
