data in PIO mode. This works around an oversight in the OMAP UART
hardware present in OMAP34xx and earlier: an idle UART won't send a
wakeup when the TX FIFO threshold is reached. This causes long delays
during data
The receive FIFO wakeup latency estimate in the omap-serial driver is
three orders of magnitude too small. This effectively prevents the
MPU from going to a low-power state when CONFIG_CPU_IDLE=y. This is a
major power management regression and masks some other FIFO-related
bugs in the driver.

Hi,
just want to ask if anybody try to boot 3.2.1 stable kernel on Pandaboard.
I try yesterday but last message which I seen was uncompressing linux
(also with enabled CONFIG_LL).
Use codesourcery 2009q1 + config from here:

Thanks,
marek
