PROBLEM: OHCI watchdog timeouts inside VirtualBox, probably due to timer wheel rework

Hello Alan (LKML on CC),
Contacting you about this on Thomas Gleixner's (also on CC) suggestion.
The short summary is that when Linux 4.8.0 (also tested with a few later
kernels) is run on a VirtualBox virtual machine with USB enabled, OHCI
fails with the log messages "frame counter not updated; disabled" and
"HC died; cleaning up". This seems to be due to the 250 ms interval
watchdog running with far too short intervals, which we think is a
consequence of the timer wheel code rework. I will refer you to a bug
filed in Launchpad<1> for a longer description.
Hope this is of interest to you.
Regards,
Michael
