Hi Peter,
This system is unable to dump all information from lspci -vxxx under root privilege, seems that it will freeze silently in the middle of that command (in both 3.13 and 3.16)

I tried to run "lspci -vxxxx | more" to see when it will freeze, it truns out that this happened on dumping:

The next line will make this happen
(The attached lspci.2 output is created manually during the "lspci -vxxxx | more" session)
