I have an x335 here that we were evaluating. Nice to hear the keyboard
problem isn't isolated to that particular model :)  I've been thinking
about fiddling with the probe order to trigger some acpi code differently
to see if that unlocks the keyboard.

I'm not getting the panic though, although this is using IDE disks and not
SCSI. I can hook up a couple to it and run a quick test, since it has a
MPT chip thats unused.

I'll have to look up the specs on the x345, but it sounds like its a Intel
chipset or at least Intel NICs versus the 335 which is Serverworks &
Broadcom.

I've been running various tests on the x35 and they are all coming back
fine.  Still don't know what the deal is with your UFS panic.  Could you
provoide the panic message and maybe a backtrace?
