Comment 11 for bug 1092102

I have just begun seeing this on my Ubuntu 13.04 Beta 2 system. It started appearing in/around initial disk fsck/mounting and renders my system unusable, with messages repeating nearly every second. Likely in pairs every second or so much the same as the original reporter.

I believe in my case, it is the same pci: id every time, and usually a few reboot attemps (hard power) and I get by without incident.

It only appeared in the last week or so, so I suspect exists in both linux-image-3.8.0-18-generic and linux-image-3.8.0-19-generic

On my HP 8560w, I have the following PCIIDs

I have not been able confirm the specific device using udevadm (assuming I need to provide the pci: id as an input) but plan to take a camera shot on a future incident to identify the specific hardware, at which point a hardware specific bug may be more appropriate.
