Re: [Gumstix-users] overo suspend and CPU throttling

[Elvis D. <elv...@ma...>]

Hi Michael,
			I've got this working by incorporating the omap-pm patches. Try the  
omap-pm recipe. You should also check the defconfig settings. You  
should also allow the mmc_unsafe_resume kernel option to avoid memory  
corruptions after waking up from resume.

As I understand, v2.6.30 merges both Tomi's DSS2 and Kevin's PM  
patches. That would be the best integrated kernel moving forward.
