>Description:
Promise SATA300 TX4 support (and possibly other similar chipsets) are broken in the current source, but works fine in the 2007-06 snapshot. Depending on your hardware setup it appears to generate lots of read/write errors. In some cases the machine will silently lock up.

freebsd-current mailing list shows that several other users experience the same thing

NOTE: build date on my kernel is from before the issue arised. i had to revert to an earlier build to stop the machine from locking up every few minutes.


>How-To-Repeat:
cvsup to current kernel and world, enable zfs and try things like creating a raidz pool, copying large amounts of data etc. must use promise sata card.
