Right, but it is gone when I check it (lspci). Here is the original

See below. The MAbort+ looks suspicious. 00:1c.1 is the parent of the
devices on bus 4.

(`lspci -nnvt` differences:)

I forgot to mention a workaround, by triggering a rescan, the
devices become alive again. Here is a log from 3.12.7 (different
from the above):

Not sure what the integrated graphics device at 00:02.0 shows up here,
but ok. This trace is shown every time the rescan is triggered (manually)
after resume.

Some times, the "enabling device" lines are not shown, and the messages
start with the following instead:

I do not know if it is relevant, but this is taken from the logs where the
