Subject: reboot fails on preempt rt 3.0.12-rt29

Hi

As you might now i am running a slightly patched rt 3.0.12-rt29 on arm pcm43 
platform. Strangely the upstart 1.3 reboot command gives me very seldom the 
error: 
"reboot: Unable to execute shutdown: Bad address"

Since the string "Bad address" is nowhere to find within the upstart or libnih 
sources i guess it is coming from the kernel sources or perror?

Reboot in turn calls shutdown -r via execv. When calling reboot another time 
it just works... The error seems so seldom that it didn't occur to me two 
times in a row for now.

Best regards
Tim
