Yeah, I see what I was missing earlier:   "(timeout)".
So it's "none of" the driver paths.

This could very well be due to one/several of the as-yet un-addressed
chipset errata for the 6081.  Someday we'll have software workarounds
for those, but I'm (still) waiting on Marvell for stuff.

I will look and see if this makes sense based on the errata info
that I have already though (under NDA).

Harri / Artem:  what type/speed of slots are your 6081 controllers in?
PCI, or PCI-X?   Bus speed?
..

Mmm.. Harri at least previously said:
Contoller is Supermicro AOC-SAT2-MV8, connected to 133MHz PCI-X slot on one computer, 66MHz 64bit PCI slot on the second machine and to normal 32bit PCI slot on third computer.
..

And Artem said:
The controller is AOC-SAT2-MV8 too.
..

As I mentioned earlier, it happens on all of my drives, 4 of 12 disks are connected to a Marvell controller, in my case:

01:00.0 SCSI storage controller: Marvell Technology Group Ltd. 88SX7042 PCI-e 4-port SATA-II (rev 02)

It is in the x16 slot.

Justin.
