Should FreeBSD handle SATA-attached flash drives?
I have added a 64GB Patriot flash drive to a 7.0 system, but it does
not seem to be working properly. Pertinent parts of dmesg.boot:

At first things look OK:
$ ls -l /dev/ad6*
crw-r----- 1 root operator 0, 88 May 3 20:30 /dev/ad6
$ file -s /dev/ad6
/dev/ad6: x86 boot sector, Microsoft Windows XP MBR, Serial 0x9e5523de
$ grep -w ad6 /usr/local/etc/mtools.conf
drive f: file="/dev/ad6"
$ mdir f:
init F: non DOS media
Cannot initialize 'F:'
Now this seems a bit odd: file(1) says it's a Windows disk, but
mdir(1) says it isn't. (Note that there are no slices, else the
initial ls(1) should have shown them.) Then, when I tried to
investigate further by examining the contents of the drive with
"od -c /dev/ad6 | more", I got one screenful of output followed
by (on console and in dmesg):
interrupt storm detected on "irq9:"; throttling interrupt source
interrupt storm detected on "irq9:"; throttling interrupt source
interrupt storm detected on "irq9:"; throttling interrupt source
interrupt storm detected on "irq9:"; throttling interrupt source
interrupt storm detected on "irq9:"; throttling interrupt source
ad6: FAILURE - SET_MULTI status=51<READY,DSC,ERROR> error=4<ABORTED>
ad6: TIMEOUT - READ_DMA retrying (1 retry left) LBA=10712
interrupt storm detected on "irq9:"; throttling interrupt source

ad6: FAILURE - SET_MULTI status=51<READY,DSC,ERROR> error=4<ABORTED>
ad6: TIMEOUT - READ_DMA retrying (1 retry left) LBA=136936
etc. etc. until I killed it with ^C. (Just entering "q", to cause
more(1) to exit and presumably stop od(1) with a SIGPIPE, did not
stop the spew of messages.)
What does this indicate? Bad drive? Controller? Configuration?
PEBCAK?
