Title:
  [Acer Travelmate 5740G] bus cycle unavailable

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have Problems when i boot my Laptop with Ubuntu 14.04. The same Problem occured on older Ubuntu Versions (12.04 to 14.04) as well as on Kubuntu and other Ubuntu derivates (e.g. Mint). When i first installed Ubuntu it worked perfectly fine for 1 or two days, but then it refuses to boot. If i try to boot from USB as well as from HDD in rescure mod, it shows:
  "
  [0.345596] perf_event_intel : CPUID marked event: 'bus cycles' unavailable
  [0.345664] ... version: 3
  [0.345725] ... bit width: 48

  [0.348871] x86: Booting SMP configuration:
  [0,348934] .... node #0, CPU's: #1
  "

  these are only the last lines, the others seem irrelevant to me.
  I use a Intel Core i 5 430M, 4GB RAM with an ATI mobility radeon HD5650
  It's a Acer Travelmate 5740G 
  It has a different HDD (not sure which i put in it) and i upgraded the BIOS which is now an InsydeH2O V1.23.

  Thanks for your help.
