Hi,
I'm running kernel 2.6.18-rc1. When CONFIG_RT_MUTEX_TESTER is enabled
kernel refuses to suspend the machine because it's unable to freeze the
rt-test-* threads. This patch adds try_to_freeze() after schedule() so
that the threads will be freezed correctly; I've tested the patch and it
lets the notebook suspends and resumes nicely.
