Thanks.

I was thinking that 'too much work' warning meant the driver was
trying to do more than allowed (as if somehow the kernel was monitoring
driver CPU consumption, and warning of an aggressive driver).

I guess it means that more work than max_interrupt_work is pending?

By the way, what is the meaning of the two status numbers (2011, 2091)?
