Description Spider (RETIRED) gentoo-dev

The machine goes into a hard lock (no network stack, no nothing) as winecfg
loads. I've isolated the change to mpu401_uart which seems to call the trigger
function infinitely.  Unloading alsa and things work again.

Reproducible: Always
Steps to Reproduce:
1. boot machine
2. start winecfg
3. Hard lock. Alt+SysRQ still work.

Actual Results:  
some printk debugging shows that the input_trigger function is called repeatedly. 

Expected Results:  
Working sound? Is that much to ask?

forgot to add:  This is still there in vanilla kernels, every release including
.14-rc kernels.
