Could you please test it under UFS, just for debugging purposes?
My experience shows that it needs a very large dataset to make the
system freeze. My last lock up happened during the pre-downgrade
backup, which means copying 200G from one disk to the other on the same
IDE interface. Your mileage may vary.
A question for the list: Is there an official "maintainer" for
IDE/ATA interface? What kind of debugging could we do to help?

If you use only linux and BSD, choose ext2fs or ufs depending on
which OS you use most. If you need windows, then you must choose
between msdosfs or ext2fs, since I do not yet know about an UFS driver
for windows.
