Subject: Commit ef83b0781a73f (PCI: Remove from bus_list and release resources in pci_release_dev()) broke TBT hotplug
Date: Thu, 30 Jan 2014 15:12:36 +0200 [thread overview]
Message-ID: <20140130131236.GW18029@intel.com> (raw)
Hi,
The latest mainline kernel "hangs" when Thunderbolt devices are
hot-unplugged to the system. I can't see any oops but after hot-unplug I'm
getting huge amounts of messages like:
[ 352.717001] pci 0000:02:00.0: PME# disabled
[ 352.717011] pci 0000:02:00.0: PME# disabled

[ 352.717133] pci 0000:02:00.0: PME# disabled
[ 352.717143] pci 0000:02:00.0: PME# disabled
[ 352.717153] pci 0000:02:00.0: PME# disabled
[ 352.717162] pci 0000:02:00.0: PME# disabled
and then the system becomes really unresponsive.
Reverting the commit in $subject makes TBT work again.
Please let me know if you need any additional information. The system I'm
testing on is Intel NUC.
Thanks.
