ACPI Error: Method parse/execution failed

Hi guys

I have been running unraid on my server for about a month off some hardware I had laying around, and loving it so far

But as my intel D945GCLF2 only has two sata ports I ordered this card: http://www.ebay.com/itm/180649569436

I installed it, and I now have four extra sata ports, and unraid sees the two new harddrives I put in, but when I try to add one of the drives to the array I get a bunch of ACPI errors:

and it goes on for hundreds of lines. Full syslog attached. (I had to delete most of the repeating lines, because it made the file too big)

What should I do?

syslog-2011-11-09.txt

Actually, I would expect it to continue for more than a few hundred lines, since it say it is an INFINITE LOOP

AE_AML_INFINITE_LOOP,

I just found the same thing while trying to diagnose a potential disk/cable issue with a drive that has been running for about 5 months without issue.

Seems these ACPI errors are quite common with the Intel D945GCLF series.  One particular google result provided an answer for me. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/495694

Post #9 mentions the setting for fan speed control.  I had this set to variable and and was getting this sequence of errors every 2 seconds with kworker running at 100%.  I shut down, changed the BIOS setting to fixed at 100% fan speed and booted back up and no longer have the errors.

I'm now running the Data-Rebuild I was when I noticed these and will see what results that brings for my drive issue.
