Hello all,

	2.4.6 crashes while calibrating the delay loop 
on a machine I've built it for, saying:

Calibrating delay loop... kernel bug at softirq.c:206!

	The machine that fails is a Cyrix MII 233MHz.
The chipset is a PIIX4.  I've tried building the kernel 
with the CPU set to 6x86MX as well as plain-jane 386, i
both have the same effect.  2.2.19 boots an runs correctly.

The output of the crash sent through ksymoops follows.
