[Hrotkó Gábor <roti@xxxxxxxxxx>]

Thanx for the response.

I had to change my board, because the K8N crashed. Now I have a A8N-E
with bios 1008. I also changed my video card to Radeon HD 4350. I also
upgraded my system as usually, and have kernel 3.2.0-52 with the most up
to date video drivers.

Since the change, I don't have system freeze.

  [ 17877.953] [mi] Increasing EQ size to 512 to prevent dropped events.
  [ 17877.954] [mi] EQ processing has resumed after 3 dropped events.
  [ 17877.954] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.
