I am test-qualifying this system for a few weeks now, and that bug only happened under very high load, apparently. So far no data corruption (data comparison is part of the test). > For debugging, it would help to have a reliable trigger, like "happens > every time I run smartctl manually" or "every time I do it while > 'cat /dev/sdc >/dev/null'" or at least "often while ". This seems to be encountered when I do an array check with mdadm, and when I adjust the min and max speed to the max. > I am able to find the PCI adapter responsible for a USB bus like this: > > $ ls -d /sys/bus/pci/devices/*/usb8 > /sys/bus/pci/devices/0000:02:00.0/usb8 Thank you.
