Description of problem:
on a Transtec 4100 dual Pentium III 550, I do not see the third PCI bus on
2.4.9-7smp but it is visible under 2.4.7-10smp.
Nothing except the kernel changed on the machine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot 2.4.9-7smp
2. network card on third PCI bus is not visible
3. boot 2.4.7-10smp
4. network card on third PCI bus is visible
the network card is the only device on the third PCI bus.

Known problem known cause
will be fixed in rawhide soon
kernel-enterprise-2.4.13-0.5 from rawhide fixes the problem for me.

uname -a, lspci -vvv, dmesg and /proc/interrupts under 2.4.13-0.5
kernel-smp-2.4.13-0.5 from rawhide works as well.
This seems to be also fixed out of rawhide.
The problem does not surface on the following (oficially released) Red Hat
kernels on the machine I ran tests on:
Thanks for the good work.
(It may be useful to change the status from closed rawhide to fixed)
