I had the pciehp driver installed, but it was a module and not loaded. I didn't have acpiphp enabled at all. Building them both in statically, appears to have papered over the cracks of the oops :-) Not loaded pciehp driver?

I guess all this work will be merged into mainline in due course, so I'll watch for them in 3.9 or later.

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. Hi Chris, What about use #modprobe pciehp pciehp_debug=1 pciehp_poll_mode=1 pciehp_poll_time=1 ? Can you resend the dmesg log and "lspci -vvv" info after hotplug device from your Fujitsu laptop with above module parameters? Thanks!

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.
