I have the same problem on my HP Pavilion dv6000 running 9.04 64 bit. Shutdown does not work in about 40% of attempts and requires me to hold down the power button to power off the laptop. It appears to happen more often when the laptop has been running for more than a day. I can reboot normally after powering down with the power button.
I have been using Ubuntu since 7.04 without ever having a shutdown problem. The issue appeared as soon as I upgraded to 9.04 from 8.10. My shutdown experience when it completes normally appears to be far slower than with 8.10. In fact my startup experience appears to be also slower. Jaunty was meant to increase the speed of the startup and this definitely is not the case for me. -- my laptop doesn't shutdown or reboot. i've posted an image. https://bugs.launchpad.net/bugs/355054 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
