Title:
xhci_hcd module turns off usb host controller on boot
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Confirmed
Bug description:
So we know this xhci_kcd was always shit in that it turns off the
console usb keyboard for long running computers and that it on abrupt
termination of Linux puts usb in a 12x slower mode. It is buggy, it
was always buggy, and its getting worse.
With Linux 4.8.0-37, this crappy software decides to halt the host
controller on boot, ie. turn off the console keyboard preventing any
boot. I cannot think of any situation where anyone would want their
host controller halted.
This is MacBook Pro 2015. So, it's already broken in UEFI-grub as it
always was, ie. every key press takes 8 seconds, but you only need
two, so you can boot in 16 s.
I tried to disable the xhci_kcd crap by using kernel parameter
noxhci_port_switch or modprobe.blacklist=xhci_hcd neither which works.
Because it has crap in UEFI, the computer will not boot any external
hard drive or usb fob. The only thing that works is Apple rescue that
gets rid of the xhci garbage, and the boot os x immediately after
that.
So the log output
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command.
- and a bit later:
xhci_hcd 0000:00:14.0: Assuming host is dying, halting host.
xhci_hcd 0000:00:14.0: HC died; cleaning up
This clown programming of Linux has to stop. Why would anyone ever want their
host controller halted?
