Hi all,

yesterday I received a reply from a manager I bought the controller
from. He was emailing with Adaptec technical support in Russia and
suggested couple of things:
	as a temporary workaround you can setup your BIOS to disable "Host
system Memory Mapped I/O above 4GB" , but note that not all BIOSes may
support it. Disadvantage of this is that RAM from 3,5  to 4GB will be
unavailable most probably.
	Adaptec is now working on a release of 2.2.8-16891 driver which suppose
to fix the issue. They promise to post it on their web site ASAP.
