After some studying it seems that grub2 is not responsible for this issue after all, but the /init phase in initramfs (or something like that I guess). That is because I can continue booting successfully after I run: /sbin/vgchange -ay in initramfs shell. I will change the question information in this respect.
So, the root cause seems to be that initramfs can't find root which is a logical volume. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/859064 Title: Unable to boot after installing 10.11 beta - vgchange needs to be run manually in initramfs shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/859064/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
