[Bug 959604] Re: [public] bad: scheduling from the idle thread!
Enabling this hotplug config provides the possibility to save more power (as well as introducing advanced error reporting and correction capabilities theoretically). Meanwhile, according to kernel document, SMP support for suspend/resume is a work in progress. I would suggest we enable this by default to find and fix any potential bugs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959604 Title: [public] bad: scheduling from the idle thread!

[Bug 959604] Re: [public] bad: scheduling from the idle thread!
Hi Seif, Another possible reason is CONFIG_HOTPLUG_CPU is enabled and I checked defconfig its also enabled. config HOTPLUG_CPU bool "Support for hot-pluggable CPUs (EXPERIMENTAL)" depends on SMP && HOTPLUG && EXPERIMENTAL help Say Y here to experiment with turning CPUs off and on. CPUs can be controlled through /sys/devices/system/cpu. So it looks to turn off cpu hotplug is also a solution if we do not support for cpu hotplug with Armada XP. Could you confirm this?

@Seif, There's nothing special that's causing the problem, it just happens on shutdown/reboot.

Thanks for the new log.

Re: [Bug 959604] Re: [public] bad: scheduling from the idle thread!
Thanks. I saw that. And it's really strange that this error disappeared after the board reboot. Could you paste a full log which shows (from boot-up) when the first error message is printed? It's helpful for us to understand which device driver is likely to cause this unexpected scheduling (within its interrupt handler).
