This is harmless but noisy; it's a bug in the dmraid patch we're currently carrying - the libdm functions always issue this complaint if the device-mapper modules aren't loaded. We should clean this up a bit more quietly.

Changed in grub2 (Ubuntu):
status:	New → Triaged
importance:	Undecided → Low

Hi, I got a solution!

This problem appeared suddenly after I recompiled with Lucid RC the Ubuntu kernel which ships with this version, 2.6.32.
I copied the configuration from my "old" 2.6.33 Vanilla (which I actually can't make working, I really don't understand what's wrong with it, but after I upgraded to RC from Beta 2 the same kernel doesn't work anymore).

I tried to recompile my kernel adding one more module, MD and BLK_DEV_DM, Device Driver>Multiple Devices driver Support> Device Mapper Support.
After I added that as module, all is fine again, and when I run an "update-grub" no more messages stating /proc/devices ecc. are printed.

I really don't know why grub (or Ubuntu?) suddenly started to behave like this.

This bug was fixed in the package grub2 - 1.98+20100614-1ubuntu1

---------------
grub2 (1.98+20100614-1ubuntu1) maverick; urgency=low

  * Resynchronise with Debian:
    - Add btrfs probing support, currently only in the single-device case
      (LP: #450260).
    - Insert partmap module in prepare_grub_to_access_device to handle
      cross-partmap setups (LP: #451585).
    - Fix verbose error output when device-mapper isn't supported by the
      running kernel (LP: #526045).
    Remaining changes:
    - Adjust for default Ubuntu boot options ("quiet splash").
    - Default to hiding the menu; holding down Shift at boot will show it.
    - Set a monochromatic theme for Ubuntu.
    - Apply Ubuntu GRUB Legacy changes to legacy update-grub script: title,
      recovery mode, quiet option, tweak how memtest86+ is displayed, and
      use UUIDs where appropriate.
    - Fix backslash-escaping in merge_debconf_into_conf.
    - Remove "GNU/Linux" from default distributor string.
    - Add crashkernel= options if kdump and makedumpfile are available.
    - If other operating systems are installed, then automatically unhide
      the menu. Otherwise, if GRUB_HIDDEN_TIMEOUT is 0, then use keystatus
      if available to check whether Shift is pressed. If it is, show the
      menu, otherwise boot immediately. If keystatus is not available, then
      fall back to a short delay interruptible with Escape.
    - Allow Shift to interrupt 'sleep --interruptible'.
    - Don't display introductory message about line editing unless we're
      actually offering a shell prompt. Don't clear the screen just before
      booting if we never drew the menu in the first place.
    - Remove some verbose messages printed before reading the configuration
      file.
    - Suppress progress messages as the kernel and initrd load for
      non-recovery kernel menu entries.
    - Keep the loopback file open so that subsequent changes to the "root"
      environment variable don't affect it.
    - Change prepare_grub_to_access_device to handle filesystems
      loop-mounted on file images.
    - Ignore devices loop-mounted from files in 10_linux.
    - Show the boot menu if the previous boot failed, that is if it failed
      to get to the end of one of the normal runlevels.
    - Handle RAID devices containing virtio components.
    - Don't generate /boot/grub/device.map during grub-install or
      grub-mkconfig by default.
    - Store grub-pc/install_devices as persistent device names under
      /dev/disk/by-id/.
    - Change priority to optional to match the priority of grub.
    - Don't display "GRUB loading" unless Shift is held down.
    - Adjust versions of grub-doc and grub-legacy-doc conflicts to tolerate
      our backport of the grub-doc split.
    - Fix LVM/RAID probing in the absence of /boot/grub/device.map.
    - Look for .mo files in /usr/share/locale-langpack as well, in
      preference.
    - Don't run /etc/grub.d/README, even if it somehow ended up being
      executable.
    - Make sure GRUB_TIMEOUT isn't quoted unnecessarily.

  * grub-common Breaks: lupin-support (<< 0.30) due to a grub-mkimage syntax
    change.
  * Renumber Ubuntu patches to start from 950 with no gaps.
  * Build-depend on qemu-kvm rather than qemu-system for grub-pc tests.
  * Use qemu rather than qemu-system-i386 (see LP #594888).
  * Fix quoting in failed_boot_menu and quick_boot patches.

grub2 (1.98+20100614-1) unstable; urgency=low

* New Bazaar snapshot.
    - Make target-related error messages from grub-mkimage slightly more
      helpful (closes: #584415).
    - Fix underquoting that broke savedefault (thanks, Mario 'BitKoenig'
      Holbe; closes: #584812).
    - Expand 'info grub' substantially, including a new section on
      configuring authentication (closes: #584822).
    - Give all manual pages proper NAME sections (closes: #496706).

* Update 915resolution from grub-extras:
    - Fix a hang with 945GME (thanks, Sergio Perticone; closes: #582142).

[ Colin Watson ]
  * Disable grub-emu on sparc for the time being.  We're currently trying to
    use TARGET_* flags to build it, which won't work.
  * Don't build-depend on libsdl1.2-dev on hurd-i386.  Although
    libsdl1.2-dev exists there, it's currently uninstallable due to missing
    libpulse-dev, and we can happily live without it for now.
  * kfreebsd-amd64 needs gcc-4.4-multilib too (closes: #585668).
  * Warn and return without error from prepare_grub_to_access_device if
    /boot is a dm-crypt device (thanks, Marc Haber; closes: #542165).
  * Make /etc/grub.d/05_debian_theme usable by shells other than bash
    (thanks, Alex Chiang; closes: #585561).
  * Remove grub-mkisofs leftovers from debian/copyright.
  * Fix reversed sense of DEB_BUILD_OPTIONS=nocheck handling.
  * Build-depend on qemu-system for grub-pc tests.

grub2 (1.98+20100602-2) unstable; urgency=low

* Only build-depend on libdevmapper-dev on Linux architectures.
  * Don't build-depend on libusb-dev on hurd-i386, where it doesn't seem to
    be available.
  * Fix printf format mismatch in disk/usbms.c (closes: #584474).
  * Fix verbose error output when device-mapper isn't supported by the
    running kernel (closes: #584196).
  * Prepend "part_" to partmap module names in grub-mkconfig, in line with
    grub-install (closes: #584426).

grub2 (1.98+20100602-1) unstable; urgency=low

* New Bazaar snapshot.
    - Add btrfs probing support, currently only in the single-device case
      (closes: #540786).
    - Fix grub-emu build on mips/powerpc/sparc.
    - Add safety check to make sure that /boot/grub/locale exists before
      trying to probe it (closes: #567211).
    - Several 'info grub' improvements, including a new section on
      configuration file generation using grub-mkconfig which documents the
      available keys in /etc/default/grub (closes: #497085).
    - Many USB fixes.

[ Colin Watson ]
  * Reorganise configure and build targets in debian/rules to use stamp
    files.  configure/* never existed and build/* was always a directory, so
    make never considered either of them up to date (closes: #450505).
  * Remove config.h.in from AUTOGEN_FILES, since autoheader doesn't
    necessarily update it.
  * Remove conf/gcry.mk from AUTOGEN_FILES, and conf/gcry.rmk from their
    dependencies.  autogen.sh runs util/import_gcry.py after autoconf et al,
    so conf/gcry.rmk's timestamp will be later than some of the
    autogenerated outputs.
  * Go back to shipping rescue images in the grub-rescue-pc .deb itself
    rather than generating them in the postinst.  This means that (a) they
    get removed when the package is removed (closes: #584176); (b) they are
    listed in package metadata, as is proper for files in /usr (closes:
    #584218); (c) grub-rescue-pc can potentially be used as a
    build-dependency for other packages that need to build GRUB images into
    installation media etc., without having to build-depend on grub-pc which
    isn't coinstallable with other platform variants and does invasive
    things in its postinst.
  * Add grub-mkrescue patch from Thomas Schmitt to allow reducing the size
    of xorriso-created images.  Use this to ensure that
    grub-rescue-floppy.img fits well within size limits (closes: #548320).

grub2 (1.98+20100527-2) unstable; urgency=low

* Always override statically-linked-binary Lintian tag for kernel.img;
    dynamic linking makes no sense here.
  * kernel.img is stripped upstream where it can be, but override Lintian's
    error for the cases where it can't.
  * Override binary-from-other-architecture for kernel.img as well as *.mod
    when building grub-efi-amd64 on i386.

grub2 (1.98+20100527-1) unstable; urgency=low

* New Bazaar snapshot.
    - Support multiple terminals in grub-mkconfig, e.g.
      GRUB_TERMINAL='serial console' (closes: #506707).
    - Speed up consecutive hostdisk operations on the same device (closes:
      #508834, #574088).
    - Fix grammar error in grub-setup warning (closes: #559005).
    - Use xorriso for image creation rather than embedding a modified copy
      of mkisofs (closes: #570156).
    - Issue an error rather than segfaulting if only some LVM component
      devices are in device.map (closes: #577808).
    - Fix typo in make_device_name which caused grub-probe problems on
      systems with BSD disk labels (closes: #578201).
    - Add DM-RAID probe support (closes: #579919).
    - Include all gnumach kernels on Hurd, not just gnumach and gnumach.gz
      (closes: #581584).

[ Colin Watson ]
  * Restore TEXTDOMAINDIR correction in grub.d files, lost by mistake in a
    merge.  Noticed by Anthony Fok.
  * Don't fail on purge if the ucf association has already been taken over
    by a different grub package (closes: #574176).
  * Add debian/grub-extras/*/conf/*.mk to AUTOGEN_FILES.
  * Remove support for the lpia architecture, now removed from Ubuntu.
  * Conflict with grub (<< 0.97-54) as well as grub-legacy.
  * Build-depend on libdevmapper-dev for DM-RAID probe support.
  * Switch to quilt.
  * Suggest xorriso (>= 0.5.6.pl00) in grub-common, since grub-mkrescue now
    needs it.  Depend on it in grub-rescue-pc.
  * Move grub-mkimage to grub-common, now that it only has one
    implementation.
  * Clean up temporary files used while building grub-firmware-qemu.
  * Make grub-probe work with symlinks under /dev/mapper (closes: #550704).
  * When upgrading a system where GRUB 2 is chainloaded from GRUB Legacy and
    upgrade-from-grub-legacy has not been run, upgrade the chainloaded image
    rather than confusing the user by prompting them where they want to
    install GRUB (closes: #546822).
  * Build-depend on libsdl1.2-dev for SDL support in grub-emu.
  * Don't leak debconf's file descriptor to update-grub, so that the LVM
    tools called from os-prober don't complain about it (closes: #549976).
    Other leaks are not this package's fault, may not be bugs at all, and in
    any case os-prober 1.36 suppresses the warnings.
  * Build-depend on flex (>= 2.5.35).
  * Build-depend on gcc-4.4-multilib on amd64.

[ Updated translations ]
  * Slovenian (sl.po) by Vanja Cvelbar (closes: #570110).
  * Vietnamese (vi.po) by Clytie Siddall (closes: #574578).

Same problem that comment #4.
I have updated the grub packages in Lucid to Maverick versions to solve this. The worst thing is that Lucid is supposedly a LTS version but Canonical only solves the bugs in newer versions! :-(

I too would like to see a fix for this bug backported to Lucid. I am using the grub packages from 10.10, but that is an inelegant solution.
