Hi,
I have an external hard drive (well, actually a case for an internal
one, but this may not be relevant) that connects to the PC via USB3.
However, I've been experiencing erratic behaviour with it. So far
there have been two issues.
One is that if I boot with the cable plugged in already, then it fails
to mount the volume (or, indeed, report that it even exists). However,
if I either remove the cable and replug it into another USB3 socket or
if I plug it in only after it's done booting, then everything is fine
and I can see and mount the volume. I'll attach the dmesg errors about
it.
The other issue is rather peculiar. When I get it mounted, doing
certain I/O tasks (I'm testing with btrfs send/receive) results in the
device disconnecting and unmounting (the key error seems to be "xHCI
xhci_drop_endpoint called with disabled ep ffff8801aced5d40"). When
it's connected through a USB2 port, I also get errors ("reset
high-speed USB device number 6 using ehci-pci"), but they don't result
in unmounting the volume. And if I do large file copying instead of
btrfs send/receive, then everything works fine even when connected
through USB3. I'll also attach the error logs in question.
I also tested this with a separate USB2 cable, and the results are the
same as when I use the USB3 cable but connect it to a USB2 port.
I'm currently using kernel 3.10.11.
Any ideas about what could be causing this behaviour with USB3?
