[Bug 1394523] Re: hp_accel causes freeze on load

  Thread Previous • Date Previous • • Thread Next 
apport information

** Tags added: apport-collected utopic

** Description changed:

  This is on an HP Pavilion x360.  If hp_accel is not blacklisted it will
  cause a freeze on load during the boot process (similar symptoms to the
  dw_dmac problem that also hits this laptop model -- I could have sworn I
  saw a bug reported on that, but I can't seem to search it now).
  
- Attached the usual suspects as a unified log, though obviously I had to
- blacklist hp_accel to get to the point where I could do that, so this is
- a log of the "fixed" system not the broken one.

  Incomplete
