Debian wheezy：machine auto booted after poweroff
Hi,
After upgrade from Squeeze to Wheezy, my notebook always auto booted
after I shutdowned it using #poweroff in gnome terminal.
Sometimes, it auto booted in 1 minutes, sometimes in 3 minutes after poweroff.
I have to use #poweroff to shutdown it once more, and it wouldn't
auto boot anymore.
I tried to go back to kernel 2.6.32-5-686, it didn't have such problem.
and I compiled kernel 2.6.39.1 using oldconfig of 2.6.38-2-686, the
auto boot still happened.
It made me crazy, any advice is appreciated.
Below is one section of syslog when the auto boot happened,nothing
seemed unusual:
