Of course, I may have missed something, but I wouldn't expect a
fundamental flaw in this logic to affect only OMAP3/4 based platforms
in such a weird way. Perhaps there is something I missed in terms of
TLB maintenance, although I would expect the existing fault handler to
take care of that.

Looks like disabling the deeper idle states for cpuidle where the CPUSs
get shut down and restored seems to work around the issue at least for
omap4. The assembly code is in arch/arm/mach-omap2/sleep44xx.S, and in
sleep34xx.S for omap3. No idea so far what might be causing this..

Regards,

Tony
