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.
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.
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.

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?
