It is said that this bug also is responsible also for Ubuntu not booting, giving following text in first 3 seconds after booting:
GRUB loading. udevadm trigger is not permitted while udev is unconfigured. udevadm settle is not permitted while udev is unconfigured. svgalib: cannot open /dev/mem which makes computer fully un-bootable. See bug #515950 (now marked as duplicate of this one) The work around is following (thanks to <slangasek>) (re)Start computer If you have grub2 installed, you need to hold down the shift key while booting. If you have grub1 installed, you need to hit escape. Now you can select the older kernel version from the grub menu The system will boot normally. Now open a console and run root command: sudo update-initramfs -u that will regenerate the initramfs for the newest kernel, and after reboot all will work in the newest kernel also. -- udev initramfs hook ignores that udevadm is disabled, copies it anyway https://bugs.launchpad.net/bugs/453678 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
