>Description:
Hello,

i compiled today the 5.2.1 and now a can reproduce the hangig of my machine. The sad thing is that the system didn't report nothing why 
it stop doing its job. The screen is black an the keyboard is stop too.
I have an RAID 1 disks on the SATA VIA 8237 chipset run on an MSI KT6 Delta ILS. If i starting to
do alot of seeks and writing of blocks on the raid1 disks this situation
entern in some minutes. The only thing to reanimate the system is the
reset button. I'am sorry but there are not any useful information.
So i have no idea to fixit.
>How-To-Repeat:
Just start to do an lot of seeks and writes.
