We don't have any boot hints for turning off tagged queueing.
That's a very basic part of the AHCI spec, if it doesn't work then
the hardware is very badly broken. That said, if serializing
the commands resulted in successful operation under linux, it might
stabilize it for DFly as well. You would need to hack the
AHCI driver to force the tags to 1 and then test to see if it fixes
the stability issues on the Vaio. The pertainant code is in
ahci_cam.c line ~378. If you are able to make it work we
could add a formal hint to allow the boot loader to specify the
behavior. It obviously can't default to 1 tag, since that
destroys the performance.<br>
<br></div>
<div>It is also possible that the BIOS might have options or
features that can be adjusted that will stabilize
operation.<br></div>

Always believed that a little courage goes a long way. So,
rather than beat around the bush much longer, I ventured the
install. At first, I got a lot of AHCI timeout errors, but they
seemed to resolve on their own. </font></div>

dump. If I weren’t such a proponent—indeed, an exponent—of
DragonFly, the whole affair would’ve been tragic. I’d
rather that DragonFly were an owner (rather than renter) on this
notebook, but it’ll do while I study for my cert.</font></div>

DragonFly works with it just by booting the image and logging in

root - it will leave your disk untouched unless you run the
