I'm getting NID not found/DMA errors on 5-STABLE with a Seagate 200gb sata drive:

This appears to be a result of 48-bit addressing. Any time a write is attempted to the sector above, I get multiple messages like this. It continues until I shut down. After a bit of googling I found this post:
http://lists.freebsd.org/pipermail/freebsd-hackers/2004-October/008821.html
and applied the change suggested. It seems to have fixed the problem, and I've had no troubles from this since Nov. 18th when I applied that patch. I'm running an Intel 875PBZ board with the ich5 controller. The drive in question is a Seagate ST3200822AS/3.01 (as reported by dmesg). So the question is, will this patch be committed anytime soon?
That looks like a pretty safe patch to make. The message says he just reduced the 48-bit trigger level by one:
Yes, I suggested that way back on the lists, and it seems to help those that had this problem. I have had it for quite some time in ATA-mkIII here as well, and since it has no real impact otherwise I've committed it to -current...
