I also have the same problem. actual kernel 2.6.32.25 + 2.6.32.26 (tried both)
It took me some month to realize the problem, because for me the "power off" at boot came very sporadically. Until today the 2nd try was always successful, but a few moments ago I had to boot 10 times to see the login-screen only at the last attempt. >From my observations the problem seems to get worse with any kernel update. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/588194 Title: Unexpected power-off during boot or when resuming from suspend -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
