System hangs on boot with Lenovo u350 notebook

[Ivan Galgoci]

System occasionally hangs on boot (I left it waiting for more then 20 minutes) during which only a typing cursor blinks at black screen. Hard reset is required. It happens like 3 out of 5 times.

System is Ubuntu 10.04.1 LTS, on Lenovo U350 notebook.

Thanks for your bug report and for your contribution to Ubuntu. In order to determine if this issue is plymouth related, please boot your computer with plymouth disabled and then shutdown to see if you can reproduce the issue? To disable plymouth for a single boot, follow these steps:

1. Hold Right-Shift during Grub boot delay to access the boot menu.
2. Select your actual Ubuntu boot line and press "e" to edit it.
3. Select the "linux" line and at the end of the line, remove "splash" and "quiet".
5. Type "ctrl + x" to boot the custom boot line.
