BUG() in asm/pci.h:142 with 2.4.13

[Christian Hammers <ch@westend.com>]

Hello

My system crashed several times now with 2.4.11-pre6 and 2.4.13
(pre6 because it was the first one I got that fixed some 2GB RAM memory
allocation bug).

2.4.13 was the easiest one to reproduce: when starting the tape backup
to a HP DDS3/DAT Streamer (C1537A) via a Adaptec SCSI Controller 
(Adaptec 7892A in /proc/pci) on a Gigabyte GA-6VTXD Dual Motherboard with
two PIII and 2GB of RAM it crashed immediately with the error attached
below. The machine was under "stresstest-simulation" load at this time.

The tape_backup.pl uses the "mt" and "cpio" commands to access /dev/nst0.

Maybe worth noting is, that the system crashed another time yesterday 
after replacing the external SCSI RAID Chassis/Controller (not the
disks in it) and just this moment with another message (see below).

Any help or hints appreciated!
