OK, so I found at least one problem with the HT1000, its sometimes=20
doesn't handle 128 sector transfers correctly, its DMA engine looses its =
wits.
The result is that it just messes up completely and barfs data all over=20
the place on the next read operation.
Anyhow the attached patch seems to work around the problem by limitting=20
transfer to a max of 126 sectors in one go, at least I have move several =
hundred Gb's around now on a zfs volume without problems, which=20
certainly wasn't possible before.
Let me know how this turns out for you!
Patch is against a clean RELENG_7 as last time, should fit both RELENG_6 =
and -current...
