Shooting trouble on a PCI bus hang

[Ansar Mohammed]

Let me do a bit more testing on this John. I will try with older (7.x) and
newer (9-current) kernels to verify that this is not a regression or
otherwise.

Also, this is a WYSE SX0 thin client with a stripped down BIOS, so I dont
expect that many other people will run into this issue.
