My mouse has a faulty cable which makes it disconnect and reconnect quite often. Since I updated my kernel from linux-3.12.0-aufs to linux-3.14.2-aufs, the USB controller it's connected to will sometimes stop working and the following messages appear in my logs: kernel: xhci_hcd 0000:05:00.0: xHCI host not responding to stop endpoint command. kernel: xhci_hcd 0000:05:00.0: Assuming host is dying, halting host. kernel: xhci_hcd 0000:05:00.0: HC died; cleaning up The xhci_hcd module is built into my kernel, so I can not even reload it. I'm currently updating my kernel to 3.14.3 and making xhci_hcd a module; I will post here if the issue is still present. Reproducible: Always Portage 2.2.10 (default/linux/amd64/13.0, gcc-4.8.2, glibc-2.19, 3.14.2-aufs x86_64) ================================================================= System uname:

Created attachment 376652 [details] Dmesg
Thank you for filing this bug; can you try and see if you can reproduce this with =sys-kernel/vanilla-sources-3.14.3, if so, also =sys-kernel/git-sources-3.15_rc4?
Is this similar to this https://bugzilla.kernel.org/show_bug.cgi?id=54991 ?
Tom: I can't really use non-aufs kernel unless I find another way to merge two directories. I'd try booting on a non-aufs kernel just to reproduce the bug but I don't know exactly when it occcurs. I assumed it was something with my mouse disconnecting so I tried reconnecting it multiple times but it did not trigger the error. Justin: I don't think it is related, I never suspend that computer.
You are right. But as alan said, there are many changes in the xhci part in 3.14. Perhaps you could report the upstream too.
