The main target systems are Intel Core i7 (920 to 950) on a MSI X58 Pro
mainboard with 24GB RAM and an Adaptec 5405 RAID controller with 3 disks
in a RAID-5 configuration. The controller is not a factor (happens also
with MD RAID).

To rule out an issue with this specific mainboard and CPU, i have also
check this (only with F15) on a Core i5 and and Asus P55 mainboard.

I could try to also confirm this on AMD X2, but it will take me a little
to setup a machine.

Gruß,
Markus
