I currently don't have access to the same laptop anymore, as I seem to
have found a workaround by locking the CPU frequency and gave the
computer back to its owner.

However, I do have another laptop with the same GPU which has the same
symptoms. Should I open a new bug and post the information there
instead?

Title:
  System freezes randomly

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Have two machines with same chip (Radeon XPRESS 200M), this one
  running XUbuntu 14.04 (with Utopic driver) and other one running Mint
  17.1 XFCE (apparently with LTS driver). Both exhibit same random
  freezing.

  When frozen, fans spin more and more (CPU on 100%, generating heat?),
  not possible to switch to console, no sysrq-combinations work, nothing
  out of the ordinary to be found in the logs afterwards.

  Have Memtested, checked SMART-info. I tried linux-crashdump on the
  Mint-machine but I couldn't find any file it would have created. Maybe
  it didn't.
