Testing the RV8803 driver [1] we are getting several "BUG: scheduling while

Having a quick look this might be from rv8803_set_time() holding a spinlock 
during the call to i2c_smbus_read_byte_data()?

Any ideas?

Yes, that is probably the case. As this is already a threaded irq, it
can probably be changed into a mutex this would solve the issue. Can you
try that? I don't have much time to do it myself right now.
