In case some more information is helpful: I have the same problem here
on a ThinkPad X31, on RELENG_5 as well as on CURRENT. The kernel
recognizes the umass device but doesn't create or mention any scsi-da
Scheduler, Preemption and ACPI don't seem to matter.
When running camcontrol rescan, it just hangs.
What's most interesting: After detaching the device, the machine often
simply reboots. Sometimes immediately, sometimes after a short while
(delays from just some seconds up to about a minute seen so far).
In some cases of luck, detaching and re-attaching the cable several
times makes the kernel recognize the da device and it works fine! Maybe
it's some weird timing problem... The reboot happens in that case as
