Hi,
"shutdown -h now" command is not working on core-image-sato image with preempt-rt kernel 3.0.4 on Romley and crystal forest BSP
I get
Warning**: could not initialize ACPI battery.
Xinit: connection to X server lost.
xinit: uexpected signal 15
Does anybody see the same problem on other meta-intel BSPs?
Thanks
Kishore.

Hi Kishore,
I don't know that I've tried that specific command.
I see the unexpected signal message when shutting down the qemux86 sato
image (non-rt) with that or the halt command, but it does shut all the
way down. In your case does the system continue to be responsive after
issuing the command?

Hi Darren,
For the non-rt "shutdown now" works perfectly fine.
For the rt kernel, after the command is issued, it tries to halt the system and hangs there forever after the connection to the X server is lost.
Thanks
Kishore.

Sounds like a legitimate bug. It works in qemux86 with -rt. I'll be able
to test an rt image on a meta-intel board in the morning. In the mean
time, please open a bug and let us know how critical you feel it is.
Thanks,

It's also worth trying the board booted UP versus SMP. We've seen
this in the past with kstop and thread migration interacting badly
on -rt. Forcing them to cpu0 on shutdown fixed those problems.
