Ubuntu 10.04 doesn't boot on kernels 2.6.32-20, 2.6.32-21

[Andrii Dutko]

Hello, all!

I have a 10.04 64 bit version, upgraded from fresh installed 9.10, a single OS on a single partition.

There are 6 options in my grub menu (apart from memtest). Depending on menu items chosen:

1) Ubuntu, with Linux 2.6.31-19-generic, Ubuntu, with Linux 2.6.31-19-generic (recovery mode)
boots just fine, both normal and recovery mode

2) Ubuntu, with Linux 2.6.32-20-generic; Ubuntu, with Linux 2.6.32-21-generic
the screen immediately goes blank with '_' cursor blinking.
Characters can be typed, no other responses.

3) Ubuntu, with Linux 2.6.32-20-generic (recovery console); Ubuntu, with Linux 2.6.32-21-generic (recovery console)
starts booting, but then hangs after line
[<~4s>] Adding 5927944k swap on /dev/sda5. Priority:-1 extents:1 accross:5927944k

Regards,
Andrii

[Yurror (yurror)]

It seem to be missing command in post-install section
[code]
update-initramfs -u -k all
update-grub2
[/code]
Boot from livecd, mount your FS and chroot into your system.
Then run commands which were previously shown.

Hey, Yurror!

I tried to do as you adviced, chrooted in the / of my fs.
First command gives the attached output.
Second:

root@ubuntu:/# sudo update-grub2
sudo: unable to resolve host ubuntu
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

Am i doing something wrong?

Hi Yurror, thanks for your suggestion. I have downloaded 10.04 rc image and boot with it. In Konsole, I have chroot to my main installation of Kubuntu (upgraded from 9.10, into this disastrous 10.04 dev build). My first attempt to update-initramfs faled, because of lacking permission to create /dev/null. So I exited and did
$ sudo mount --bind /dev /mnt/dev
$ sudo mount --bind /proc /mnt/proc
$ sudo mount --bind /sys /mnt/sys
(reference: http://ubuntuforums.org/showthread.php?t=1377010)
And then re-chrooted and update-initramfs again. This time it succeeded. Update-grub2 succeeded too.

So I exited the console and reboot out of the live session.

But my 10.04 installation still hangs with blank screen when rebooting. It does not seem to be a problem with Grub2, but rather with the kernel (2.6.32-xx I guess).

Could anyone confirm if it's all the same problem with https://answers.launchpad.net/ubuntu/+question/107521

Thanks.

Just murmuring: what kind of release candidate fails to boot even from the beginning?

[MilchFlasche (robertus0617)]

I have finally managed to update my 10.04 (upgraded from 9.10 last night), but it still hangs at booting.

A clean installation of 10.04 RC on the same machine (luckily I've got a spare partition) does boot, and here I'm typing this message in this clean 10.04. But I still hope to revive my previous installation. I'm willing to provide message logs if required. Thanks.

[Andrii Dutko (4ugeistr)]

Eventually I had to make the machine work (it isn't mine) so I reinstalled from a fresh RC disk.

A fresh install works fine, but I won't be able to provide any more information concerning the bug.

Same bug here. 10.04 rc hangs at /dev/sda5. Priority:-1 extents:1 accross:!
Tried to reinstall GRUB2 and the commands mentioned above in chroot mode. Still dead.
But: It worked fine for about 4 or 5 reboots. And it rebooted very quick.
Then, suddenly after some changes on evolution and appearance it stopped. Machine is a brand new
Lenovo SL510.

[iFritz (pakoenig)]

Update: I just chrooted into the system and did a "apt-get upgrade" after a apt-get update"!
After a reboot the following error comes up:

mount: mount point /proc/bus/usb does not exist
mountall: mount /proc/bus/usb [395] terminated with status 32
mountall: Filesystem couls not be mounted: /proc/bus/usb
fsck from util-linux-ng 2.17.2
/dev/sda1: clean, 143498/14917632 files, 17009922/59639296 blocks

[iFritz (pakoenig)]

Update2: Now i got it working! Its the Vritualbox causing my problem. Referring to this thread: http://forum.ubuntuusers.de/topic/upgrade-zu-10-04/#post-2456704
i deleted the entry for VB and Ubuntu is running like charm!

Hi Andrii,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 565938

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
