Thanks for the report!
What device is 00:00.2? Does it work? If not, did it ever work,
i.e., is this a regression? If it's a regression, what's the newest
kernel you know of where it did work?
Can you please attach a complete dmesg log and output of
"sudo lspci -vvv" to the bugzilla?
Can you also add links to any related bug reports you're aware of?
