Well... I guess there's no bug as such. The simple-pm-bus just uses a 
lot more stack. Looking at the reports from CONFIG_STACK_TRACER, in the 
good commit the biggest stack is in USB probing with depth of 4896. With 
01d7136894410a71932096e0fb9f1d301b6ccf07, and a debug print in 
omap_i2c_xfer_common, I can get to 7544.

I don't know what to do about this, so I'm giving up for the time being 
and "fix" it for myself by increasing THREAD_SIZE_ORDER.

Well... I guess there's no bug as such. The simple-pm-bus just uses a 
lot more stack. Looking at the reports from CONFIG_STACK_TRACER, in the 
good commit the biggest stack is in USB probing with depth of 4896. With 
01d7136894410a71932096e0fb9f1d301b6ccf07, and a debug print in 
omap_i2c_xfer_common, I can get to 7544.

I don't know what to do about this, so I'm giving up for the time being 
and "fix" it for myself by increasing THREAD_SIZE_ORDER.
