Thus spake Tony Lindgren (tony@atomide.com):

Please everybody using omaps with mainline give a test for the
merge of the various fixes planned. I've done a branch with
v3.3-rc3 + Russell's fixes + Paul's serial port fixes + fixes
that I've queued up.

If you still see problems with compiling, booting, or slow serial
port, please post the issues to linux-omap and LAKML lists
immediately.

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*).

dmesg: http://tonya.fnordsoft.com/omap-testing/testing-dmesg

I also get these warnings when compiling:

take care!
