SETFEATURES SET TRANSFER MODE taskqueue timeout.. Error occuring constantly.. Please help!!

[Kristian Rooke]

Hi,

I have a PC/box with 5 disks in it that I am using as a fileserver and
I recently upgraded some hardware and installed FreeBSD 7.0-RELEASE.
Previously I had a RAID PATA IDE controller on the motherboard (was
not using RAID functionality though), but I when I upgraded I had to
use a PCI IDE controller, due to the lack of PATA ports on the new
motherboard.
Now when I am attempting to write files, or do anything more than just
browse filesystems on the drives ad4-ad7, I get multiple occurrences
of the errors below. After these errors occur the kernel panics and I
need to perform a hard reset to get the server back up again.

I have taken a read through some previous conversations, but I can't
seem to find the answers I'm looking for.

I've changed the IDE cables and the PATA controller and it is still
not making any difference.

I also added hw.ata.ata_dma=0 to /boot/loader.conf as recommended in a
wiki I came across, but if anything it made the issue even worse.

Can someone please help?

Thanks,
Kristian
