Bug Description

Binary package hint: linux-source-2.6.28

I use a Dell XPS 710 with Ubuntu Jaunty installed on. System reboot freezes on
"[1774.527497] Restarting system." but nothing happens. I have had this problem since edgy, now I had some time to look at it. solution is to add "reboot=b" as a kernel option.
dmidecode output is attached
