Subject[regression] pciehp hang on hp ia64 rx6600
Hi Mark, Kristin,

On my hp ia64 rx6600, 'modprobe pciehp' causes lockups and a
system hang on 2.6.25-rc4. My system often hangs when only pciehp
is loaded and my console is sitting idle, but I can accelerate
the hang 100% of the time by immediately doing a 'modprobe
acpiphp' right afterwards.

I have bisected the hang down to this commit:

0a3c33d77ff7ad5b988997536a8f09c49e35ad20 is first bad commit
commit 0a3c33d77ff7ad5b988997536a8f09c49e35ad20
Author: Mark Lord <lkml@rtr.ca>
Date: Wed Nov 28 15:11:28 2007 -0800

PCIE: fix PCIe Hotplug so that it works with ExpressCard slots on Dell notebooks (and others?) in conjunction with modparam of pciehp_force=1.

Fix pciehp_probe() to deal with ExpressCard cards
that were inserted prior to the driver being loaded.

Reverting this commit makes the hang go away (and I can modprobe
pciehp / acpiphp again without problems).

It looks like the patch is calling pciehp_enable_slot() if the
slot is occupied. I'm not sure exactly what should be happening
on my machine (it's late here ;), but I can try and do some more
thinking tomorrow.

Console log and lspci -vv output follows. Please let me know what
else you might need.

Thanks.
