I know about this problem, I'm working on a proper fix. Thanks for your

Can you send me the PVR value for both of these CPUs
(cat /proc/cpuinfo) ? I can't find right now why they would lock up
unless the default idle loop is _not_ run properly, that is for some
reason, NAP or DOZE mode end up not beeing enabled. Can you send me
your .config as well ?
Note that when CONFIG_BDI_SWITCH is set, they both end up disabled because nap & doze seems to perturb the BDI on some cores.
So there is a problem in that case ....
Finally, try that patch and tell me if it makes a difference.Yup
- Without it hangs (not really, it's still half running but serial output is stuck
due to no interrupts)
- With it it works
