OK, it looks like you do have input, what you do not have is X

I am not sure why radeon reports lockup with that patch; serio uses
system_long_wq to schedule its long-playing works and the only other
user of system_long_wq seems to be sata, but then concurrency management
should take care of them sharing the workqueue.

Tejun, do you have any ideas here?

Thanks.
