Hi Chris,
try to include in kernel only acpiphp and omit pciehp. Don't use modules but include
them statically. And try, in addition, check whether "pcie_aspm=off" in grub.conf helped.
Thanks for the tip. 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 :-)
The best would if you subscribe to linux-pci, and read my recent threads
about similar issues I had with express cards with Dell Vostro 3550. Further, there is
a lot of changes to PCI hotplug done by Yingahi Liu and Rafael Wysockij, just browse the
archives of linux-pci and see the pacthes and the discussion.
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.

Hi,
I've today taken delivery of a WinTV-HVR-1400 expresscard TV Tuner and got an Oops when I removed from the expresscard slot in my laptop. 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. I have turned debugging on in the dib700p and cx23885 modules via modules options in /etc/modprobe.d/hvr1400.conf;
2. the .config file for the kernel that oopsed.
3. the text of the oops message. I've typed this up from a photograph of the screen because the laptop was locked up and there was nothing in the log files. Apologies for any typos, but I have tried to be careful.
Assuming the answer isn't don't do that, let me know if I can provide any additional diagnostics, test any patches, etc. Please, however, cc me as I'm not subscribed.
Chris
