I had the pciehp driver installed, but it was a module and not loaded. I didn't have acpiphp enabled at all.

Those discussions are way above my level of knowledge. I guess all this work will be merged into mainline in due course, so I'll watch for them in 3.9 or later. Unless, of course, there is a tree I could clone and help test the changes with my laptop and expresscard. Hotplug isn't working at all on my Fujitsu laptop, so I can only get the card recognised by rebooting with the card inserted (or by writing 1 to/sys/bus/pci/rescan). There seem to be a few reports on this in the kernel bugzilla, so I'll look through them and see what's being done. Thanks again.

I will quite understand if the response to this report is "don't do that!", but in that case, how should one remove one of these cards? >> >> I have attached three files: >> >> 1. the dmesg output from when I rebooted the machine after the oops.
