Assuming you mean from poweron to crash, right?

I've done some tests. I can let it sit for minutes on the etherboot 'Boot
from (N)etwork (D)isk or (Q)uit?' prompt. From the moment it starts FILO's
default kernel, it doesn't last much longer than 11 to 14 seconds. I have 2
datapoints with almost 14 seconds, one with just over 13 seconds and 2 with
just over 11 seconds. Of course these measurements are not very precise since
I had to push the timer buttons manually.

T 000:00:13.248
T 000:00:11.328
T 000:00:11.532
T 000:00:13.864
T 000:00:13.715

The biggest part of that time is spent right after it prints 

  ACPI: Unable to locate RSDP

There is no output for easily 5-6 seconds after printing this.

What do you think, watchdog timer or not? I've attached another (longer)
bootlog with many boot attempts.
