Kernel config

I keep seeing various errors in dmesg which I will show below, and occasional
disconnects. I've tried it on two different computers and it's only happening
on one of them so I don't think the hardware itself is at fault, but I'm sure
people on the list here will know a lot more about it than I do.


Sometimes I get the error "ERROR Transfer event TRB DMA ptr not part of current
TD" as well, and occasionally "parse_audio_format_rates_v2v3(): unable to find
clock source (clock -71)" but often it's just disconnecting the port, which
then reconnects within a second or so.


It's using the xhci_hcd driver, I've looked in to disabling xHCI in the BIOS
after some searching on the web but this laptop doesn't have any option to do
that, and it's also using that driver on the other laptop that doesn't seem to
have this issue.

I am attaching the current kernel config, as well as some dmesg extracts with
'module xhci_hcd =p' set in /sys/kernel/debug/dynamic_debug/control.
