panic in uas_data_cmplt()

Dear all:

The kernel version is 3.16.1-1-ARCH

Today I keep getting this panic when booting up.

It might be that the UAS device was in some strange state, because that after I unplugged and power-cycled the UAS, everything went normal again.

Does anyone know what's the root cause of this issue?
Or could anyone provide some instruction on how to debug this issue?

There seem to be some issues in the error handling paths of the uas driver. I plan to rewrite them completely for robustness and go through them with a fine comb to fix any possible bugs while at it.

I'll send out a mail when I've a new version ready for testing.

Regards,

Hans
