It seems that this problem is not reproducible without splash. I didn't experience a crash since i removed the "splash" option from grub.
Also, pressing "Esc" has no effect on lock ups. I edited my /etc/init/mountall.conf, but i don't know where to find the debug informations. -- System fails to boot with plymouth installed (ATI driver) https://bugs.launchpad.net/bugs/540706 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
