Subject: Regression in next-20100618

Hi Alan,

I have a regression in the next tree from 20100618, the prompt
freezes on the U8500. Drilling down with git bisecting found:

    serial: Use block_til_ready helper

    Our code now rather closely resembles the helper, so switch to it.

Reverting the commit makes the problem go away.

This platform is using drivers/serial/amba-pl011.c

Any ideas I could try out to help troubleshooting this one?
It could be that you're provoking some bug in amba-pl011.c.

Yours,
Linus Walleij
