This is definitely RAID/LVM related. On my 14.04 system with a ext4 boot partition I don't get the error, but on another system that's fully LVM I do get the error.
Has anyone come up with a grub config workaround to prevent the delay on boot? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1274320 Title: Error: diskfilter writes are not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1274320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
