What is the problem with 5.4 and ATA drives? I am running the latest release
of FreeBSD 5.4-RELEASE-p11.  I have two basic ATA drives, no raids and no
scsi anything. Every now and then under a bit of load the harddrive freezes
with either a kernel panic or a Write_DMA error. I have to reboot the
machine and run fsck -y to recover. Sometimes I have to run it twice.

As per several posts that were similar I have the following uneffectively
enabled in my loader.conf file.

hw.ata.ata_dma=0
hw.ata.atapi_dma=0

However, this hasn't fixed the problem. From the amount of issues similar to
mine I am going to take a whack at the fact that I don't think it is
strickly a DMA or drive issue. The DMA issue is just the result of a deeper
underlying problem. Maybe something in the kernel or drivers. This same
issue is relevant for 3 brand new Supermicro machines all running nearly the
same Western Digital drives. 4 drives are 200GB WDs and 1 is a 160GB WD. All
with brand new cables. Since this is all brand new equipment please don't
pass this off as a bad cable. It isn't.

As for the drives I have smarttools running on these systems now and there
are no bad sectors and the drive health is all clean. Absolutely no issues
as reported by smarttools. No changes in any of the attributes at all.

Here is some more info:

Let me know if anyone wants more info.  Any help or insight that anyone can
provide would be great. These machines went are production as of just
recently and these issues didn't appear until put under some load. So
basically I am now screwed. HELP!

Cheers,
