The problem is not caused by any changes in the Linux OHCI or USB code (and obviously the VirtualBox USB emulation did not change either). It's almost certainly triggered by the timer wheel rework which went into the 4.8 kernel.
There is a watchdog routine in the OHCI driver which is meant to be run every 250 milliseconds and check whether the frame counter is updating (which happens at most every millisecond). In Linux 4.8, the watchdog routine can be run again after 4 milliseconds or possibly even less. If it sees the same frame counter value twice, it declares the HC dead and unloads the driver. That is the problem. The "irq 22: nobody cared" and subsequent "Disabling IRQ #22" errors are caused by a bug in VirtualBox which is only triggered by unloading the OHCI driver. The "frame counter not updating" error is the real issue and highly likely to be an unintentional change in Linux 4.8 behavior. As far as the OHCI driver is concerned, it's OK to run the watchdog routine later than requested, but it must not be run too soon. And yes, https://bugs.launchpad.net/ubuntu/+bug/1635012 is almost certainly the same problem occurring on physical hardware. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1634737 Title: ohci-pci: frame counter not updating; disabled Status in linux package in Ubuntu: Confirmed Status in linux source package in Yakkety: Confirmed Bug description: I've been running Ubuntu 16.04 inside a VirtualBox (version 5.1.6 r110634 (Qt5.5.1)) running on Windows 10 Home (version 1607 os build 14393.321) host without any incident until I upgraded to Ubuntu 16.10. I have a USB to Serial converter (pl2303) connected to a development board that is handled by the Ubuntu Linux Kernel. After upgrading to Ubuntu 16.10 the ohci-hcd driver reported that the "frame counter not updated; disabled" followed by "HC died; cleaning up" which would kill my terminal application (kermit) that was connected to the pl2303 device. When the issue was first noticed, I rebooted the Linux virtual machine and booted the previous kernel (4.4.0-43-generic) and was able to use the pl2303 to communicate to my development board just fine. I switched back to the 4.8.0-22-generic kernel and the ohci-hcd driver reported the same problem. I looked at the differences between the ohci-hcd.c and pl2303.[ch] drivers between 4.9-rc1 and the 4.4.0 linux kernels and the pl2303.[ch] files didn't have any changes, and only a couple of changes were made to ohci-hcd.c but nothing that would indicate an issue.
