SubjectRe: [PATCH 2/3] netpoll: netconsole
> No, haven't encountered it. Which lock are we talking about, specifically?

The hardware register lock of the low level device drivers.

It's a different lock for each driver.

They take it usually in all functions that access hardware registers,
including poll.
