PCI: Failed to allocate resource in 2.4.20pre10 and 11 - broken IRQ-router?

[Andreas Hartmann]

Hello all,

I'm using an IBM Thinkpad T21 with a dockingstation, which has an own additional
ide-controller. At this controller, one more ATA-IDE hd is connected (/dev/hde).
dmesg with kernel 2.4.19 looks like this (correct version):

If I use 2.4.20pre10 or 11, the kernel can't find the additional ide-controller in the dockingstation no more.
