There has been a bug discovered
It was acknowledged by Intel and recalls have been ordered.
However, since it was reported to only occur on buses beyond 0 and 1 I do not know if my hard disk which is the sole one on a laptop can be affected (it also has only one more dvd drive).
Does anyone know the exact symptoms of the problem, if it manifests itself?
I currently get some "thrashing-like" effects on the disk but until now I considered them a fault of the disk itself (the RAM is plentiful).
