With the testing branch, my serial port is still very slow.
The console is set to 115200, dmesg takes almost a minute to print out.
I'm testing on a beagleboard-xm, which has the DM3730.
(if I change omap2_pm_idle() to never call omap_sram_idle() things improve *a lot*).

I also get these warnings when compiling:

with this gcc:

take care!
