As Tim indicates there is an element of a race to this issue. On my test system and upgraded (Maverick -> Natty) system the issue was not reproducible in 20 reboots. I scratch installed from the same Natty image and the issue was instantly reproducible. In testing removing the ureadahead pack seems to render the machine bootable for the next boot. All of this tends to indicate that this is indeed a boot race.
It is reminicent of the framebuffer open races we experienced in Maverick. Cirtainly in boots where things work there is no sign of the vesafb being used, whereas it appears to be painted by plymouth in most of the failed boots. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Andy Whitcroft (apw) ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux (Ubuntu) Status: Confirmed => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683775 Title: Natty Alpha 1, i915 has blank screen after boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
