After booting with "acpi_skip_timer_override" there appears to be a problem with the CDROM driver at the second stage (probably caused by some IRQ problems - I also tried booting with "nodma", but that went even worse).
The CDROM drive makes a sounds like the CDROM media might be damaged and the installation halts, so I burned a new imaged and checked the md5sum - and the install CD is fine. I attached a screendump, but I doubt it's helpful. Booting with the "enable_8254_timer" option seems to screw up the CDROM driver even worse, and the annoying sound starts already while loading the ramdisk image. ** Attachment added: "screendump from install" http://librarian.launchpad.net/4224992/screendump.jpg -- freeze at startup https://launchpad.net/bugs/38263 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
