Hello all,
Hope this is the right place to report a bug; if not, please direct me
to where it should go.
I am running a mainline kernel build by the Ubuntu mainline PPA, on a
2015 Macbook. It is being tainted by use of the vboxdrv module. I am
repeatedly getting errors on xhci_hcd irq handler.
There is detailed data below. I generally associate the error with
plugging in the external mouse, but I can't reproduce reliably.
The relevant trace in dmesg are listed below:
