I tested with Linux 4.0rc2. Without acpi=off, my system froze during the boot process. With acpi=off set, I was able to boot into X-Windows, log in, and start my web browser. Soon thereafter, however, my system froze up complete: mouse pointer did not respond, and no key combination provoked any response. I tried switching to a text console immediately after boot, which also resulted in a complete system freeze at some point. Note that even Alt+SysRq commands were non-responsive.
After leaving the system frozen for enough time (~5 minutes), it rebooted itself. I'll be happy to provide whatever logs would be useful, just let me know what would help. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists- upstream-4.0-rc2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1424526 Title: Unable to boot from installation media To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1424526/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
