Still no luck with atacontrol...
Is there any way to debug this further ?? I've tested the disk, the SATA
cables are new... I've had similar problems with other motherboard... I dont
think this is related to hw problems, but rather a softwareproblem that
needs to be solved, this is not something one can call stable ;)
So, any pointers how to enable more debugging or anything that could give
some clues?
I don't have a whole lot to add to this thread, but have changed the subject
to make sure that the right people are reading this. This is likely either a
hardware problem (motherboard/cable/drive) or driver problem. GEOM and the
mirror driver seems to be behaving as desired (it detaches a drive reported by
the driver as being bad). Could you post the dmesg -v output for the probing
of the ata controller and driver?
