[Gumstix-users] UART kernel 2.6.34 : "too much work for irq72"

[DavidC <dav...@ho...>]

Hello,

I have a problem with the UART on the overo board.

I need  to receive data at 460800 bauds. It works very well with kernel 3.0
from Sakoman.
But with the kernel 2.6.34 for caspapx (which I need for my application)
when i try to read from serial port It says "too much work for irq72"
continously. What does it mean?

I know that the driver for serial communication changed between the two
kernel. It was serial8250. It is now omap.serial. 

Maybe backporting the driver in 2.6.34 will solve the problem but I really
don't know how to do this. Have you some info about doing it?

Thanks!

David Caruso
