As a workaround until this makes it to the various distributions,
would it be possible to create a config file that enables the quirk,
something like:
> cat /etc/modprobe.d/xhci.conf
# Enable XHCI_AVOID_BEI (= 1<<15)
options xhci-plat-hcd quirks=32768
I tried this using "xhci-plat-hcd" and "xhci-hcd", but neither appeared to work.
Thanks,
Alistair
