2.4.20 kernel crashes while scanning partition list

[Peter Karlsson]

I am installing Debian Linux on my new Athlon XP PC, and I have
problems with the 2.4.20 kernel crashing on boot. I can successfully
boot using the 2.4.18 kernel build that is included with the Debian 3.0
install cds.

The problems seems to stem from my use of Promise FastTrak133 RAID
controller (yes, I know they say it sucks, but it's what is integrated
on the MB). In 2.4.18, I can get ataraid working, although I have to
specify the address to the IDE controller manually. 2.4.20 picks that
up automatically, but crashes when enumerating the HD partitions
(reproducible every time).

The crash output looks like this (I had to write it down by hand, hopefully
there will be no typos):

The corresponding System.map file can be downloaded at
<URL:http://www.softwolves.pp.se/tmp/2.4.20/System.map-2.4.20> and a
partition list from sfdisk -l can be found at
<URL:http://www.softwolves.pp.se/tmp/2.4.20/partlist.txt>.

The motherboard is a MSI KT3Ultra2 ("VIA KT333 chipset based"), the CPU
is an Athlon XP2200+, and the machine has 1 Gbyte of RAM.

Any help in getting this resolved would be greatly appreciated! I
really would like to move on from my old K6 machine...
