Nope.

The old CMD640 should be avoided at all costs, the newer CMD646
has problems thats taken care of pr revision. The newer CMD648/649
are OK but are not the best performers...

This is probably related to the inverted sense-test that was
recently fixed.

FWIW: the CMD640 series of chips is well known to mung DMA, if
an interrupt occurs during a transfer.  I can't say for certain
that the CMD649 has this problem, so you might want to look at
the vendor errata for the chips.  Personally, I avoid the CMD64x
controllers entirely, so as to avoid getting a bad one, since I
have no idea if there is actually a good one in existance.  8-(.

I just committed a fix for that.

Yet another ATA-related Kernel trap 12 :-(

[Vladimir Kushnir]

Setup: Fujitsu MPG3409AT E disk on external CMD649 controller (the only
HD). Kernel trap while booting with timeout for ad0 device. Setting
"hw.ata.ata_dma=0" solves the problem. Sources last cvsupped last night
(after the last ATA-related commits). Dmesg output attached, but that's
about all I can provide - no serial console here.
