Hello,
My PCIe host bridge is supposed to support AER, so I enabled
kernel support, out of curiosity. For these tests, I plugged
a USB3 card into the PCIe slot.
I see two classes of reports.
1) When the system is idling, with no USB device plugged into
the PCIe card, I occasionally see these:
[ 5003.638675] pcieport 0000:00:00.0: AER: Multiple Corrected error received: id=0000

1105:0024 is the rev1 host bridge.
1105:0028 is the rev2 host bridge.
I'll let a rev1 host bridge idle for a long time, but I don't
remember seeing these reports on rev1.
2) When I unplug my USB3 Flash drive, I always get some kind of
error from the USB framework, and sometimes they are coupled with
AER messages.

Should I worry over these reports?
(The first set looks harmless, the second one looks bad.)

I'll try enabling AER on the legacy kernel (3.4) to see if I get
the same behavior.

And I also see a third kind of report:

I'll try enabling AER on the legacy kernel (3.4) to see if I get
the same behavior.
