I think this is a(nother) VIA chipset bug. (Or possibly an AMI BIOS
bug?) I had exactly the same problem. The cure was to change the
BIOS setup to disable the APIC. When 2.4.20 boots, it re-enables
the APIC and is happy. From dmesg:
Linux version 2.4.20 (pigeon@pigeon) (gcc version egcs-2.91.66 19990314 (egcs-1.1.2 release)) #1 Fri Jan 17 20:49:00 GMT 2003

Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!

Using local APIC timer interrupts.

..... CPU clock speed is 1533.4371 MHz.
..... host bus clock speed is 266.6846 MHz.
Without disabling the APIC in the BIOS, it gets as far as the first
ESR value, which it gives as 00000002, and then locks up - just like
yours.
OK, yours is fixed, but you may want to get your APIC working, and
someone else might like to know!
