Hi all,

I have pulled kernel from linux-omap git's 2.6.30 branch (
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=shortlog;h=omap-2.6.30
) and trying to boot on my OMAP3 beagle board (Rev. B4). It got stuck
at Calibrating delay loop.....

From the below log I found that the jiffies value is not getting
incremented and couldn't able to come out of the loop

I found that the OMAP_TICK_GPTIMER which is responsible for the system
tick from the arch/arm/plat-omap/Kconfig is missing in 2.6.30. Can you
guys put some light on what is going wrong ?

Thanks and Regards,
Venkat Raju.



Hi Raju,

Use a newer compiler. e.g. 2009q1
