Title:
HP Probook 450 usb ehci breaks between 3.13.0-36 and 3.13.0-37
Status in linux package in Ubuntu:
Incomplete
Bug description:
Release: Ubuntu 14.04.2 LTS
Package version: linux-image-3.13.0-37-generic
What expect to happen: USB to work after boot-up
Whap happened instead: dead USB, no dmesg messages when unplugging or
plugging in USB devices.
HP Probook 450 USB support got broken since 3.13.0-37. Ubuntu 14.04.2
LTS
Similar but not identical to problems as described in
https://bugs.launchpad.net/bugs/1072918.
All USB ports dead. dmesg shows ehci_hcd died. cleaning up.
By passing extra kernel parameters using grub menu:
ehci=noirq (or was that acpi=noirq) makes it work but that breaks onboard
ethernet.
also tried with tried iommu=soft (didn't work)
Tried all kernel images from 3.13.0-37 to 3.13.0-52 .. all the same
result: broken USB.
had to back-step to 3.13.0-36 ...
Just thought I'd mention, that might affect other HP Probook models as
well.
kernel modules affected: xhci_hcd, hid_generic, usbhid, ehci
