I've updated git tree to  commit 33af79d12e0fa25545d49e86afc67ea8ad5f2f40
(and using two extra patches - for led_trigger & poweroff issue)

I wanted to test the new sysprof feature

- It looks like the machine is rebooting after memory suspend/resume
(if I'll get a trace I'll make a new post)

- selinux=off     doesn't work anymore    - had to use selinux=0

- I've got this Warning from the boot  (attached configuration file)
