serial8250: ratelimit "too much work" error
Running a serial console, if too many kernel messages are generated within a short time causing a lot of serial I/O, the 8250 driver will generate another kernel message reporting this, which just adds to the I/O. It has a cascading effect and quickly results the system being brought to its knees by a flood of "too much work" messages. Ratelimit the error message to avoid this.
