[Bug 1007752] Re: Most recent grub update uses root=/dev/sdX for boot image, may fail to boot

[Daniel Smedegaard Buus]

Hi, sorry for the very long delay (holiday! yay!) :)

Returning this weekend, I decided to get rid of my secondary NVIDIA card
and use this box solely as an HTPC machine (at least GUI-wise, it's
still a server otherwise ;) ).

Tons of updates, and I removed my SII3114 PCI card and replaced it with
a PCIe-based 3132 one now that I had the vacant PCIe slot.

During this, a lot of drives changed ports, including the system one. No
problems occurred.

So, I cannot say if this was due to an upgrade, if my problem was just
some weird cosmic ray hitting me, or what, but there's no problem
anymore.

Sorry to keep you busy, and thanks for everything. I'm marking this
invalid.

Cheers,
Daniel

Title:
  Most recent grub update uses root=/dev/sdX for boot image, may fail to
  boot

Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  Hello :)

  The recent update (today) of grub,
     grub-pc:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
     grub-pc-bin:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
     grub-common:amd64 (1.99-21ubuntu3, 1.99-21ubuntu3.1)
  killed my grub, apart from also looking strange (used to be gray background, and a nice logo splash when booting, now black background and just low-res text when booting).

  The BOOT_IMAGE command defined root as - in my case - /dev/sdq2, while
  at boot it would be /dev/sdb2. Also, this might not stay the same
  regardless, and as I understand it, this should point to either a
  partition UUID or perhaps /dev/disk/by-id/something-or-other?

  In any event, as it stands, all boot options ends with busybox and an
  initramfs prompt. Editing the grub command and fixing the root= to the
  right path before booting will send me normally into Kubuntu where I
  can (hopefully) fix the problem manually.

  Cheerio :)

  Daniel
