[Bug 1537183] [NEW] [iwlwifi] Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff)

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Was using wireless on my x220 thinkpad, took it out of the dock and
wireless stopped working. I couldn't remove and re-insert iwlwifi to get
this working. I had to do a complete reboot of the system before
wireless worked again.

Title:
  [iwlwifi] Timeout waiting for hardware access (CSR_GP_CNTRL
  0xffffffff)

Status in linux package in Ubuntu:
  New

Bug description:
  Was using wireless on my x220 thinkpad, took it out of the dock and
  wireless stopped working. I couldn't remove and re-insert iwlwifi to
  get this working. I had to do a complete reboot of the system before
  wireless worked again.
