Subject: Machine automagically reboots with 2.6.23-rc2-mm2

Hi,

My machine reboots automatically after a few seconds of booting 2.6.23-rc2-mm2.
I've tried several ways to debug the problem, but I've had no success.
I am not sure if this problem has been reported already, a few simple searches
did not indicate that the problem had been reported

2.6.23-rc1-mm1 did not have this problem.

.config is attached with this email.
