Report for a number of issues.

[Thomas Schwinge]

Binary package hint: linux-image-2.6.20-6-generic

D E F E C T R E P O R T
=========================

... for a 2007-02-01 update from an up-to-date Edgy system to pre-Feisty.

I had expected this to be a more-or-less feasible thing to do, as Feisty's release date is getting nearer. I updated using ``gksudo 'update-manager -d'''.

One-line summary: even worse than it was when I was updating from Dapper to pre-Edgy.

The system is a IBM (now Lenovo) ThinkPad T42. Nothing spectacular.

Issues:

* The sound hardware isn't recognized anymore.

* Suspending to ram stopped working.

No matter whether I press `Fn-F4' or select the item in `gnome-power-manager''s list, the screen goes black, the moon-light begins blinking -- as is used to -- but then -- not as it used to -- the screensaver's unlocking password dialog comes up again. The moon-light keeps blinking even if I log back into the system again. Exactly the same story for suspending to disk.

* The hanging-while-booting problem is still not fixed.

See <https://bugs.launchpad.net/ubuntu/+bug/74522>.

From `dmesg', mind the time stamps:

* `initrd.img'.

In `/boot/', the `initrd.img' that corresponds to the previous (Edgy) kernel version was truncated to zero length during the installation process. Restoring it with the Feisty `update-initramfs' and friends is not possible because the ``udev hook script requires at least kernel version 2.6.19''.

* Disk space.

The free disk space required (that the installer had calculated) was not enough. I noticed quickly enough and was able to delete some files from the root file system to circumvent an abortion of the upgrading process because of lacking disk space.

To make sure that it wasn't some sort of transient error, I rebooted once more with the Feisty Linux kernel and could reproduce all the kernel-related issues.

After having restored the destroyed Edgy Linux kernel's `initrd.img' from another machine I rebooted with the Edgy Linux kernel and everything save the ``hanging-while-booting problem'') is ``fixed''. This is of course neither a real option nor a solution. (... but the reason why I filed
this report against the `linux-image-2.6.20-6-generic' package.)

Feel free to fork this report into different ones or tell me to. I will happily try to help.

[Dennis Kaarsemaker (dennis)]

Thomas,

Thanks for the detailed report. Splitting it into separate reports, as you suggest, would be very much appreciated.

[Ben Collins (ben-collins)]

The main bug here (for the kernel) is the atheros crash. All the other kernels problem cannot be reviewed until the crash is fixed (which it will be in the next kernel upload).

Once that is fixed, reconfirm the other problems. They were likely caused by the unstable state of the kernel caused by the atheros crash.

The other bugs, please file against appropriate packages.

[Launchpad Janitor (janitor)]

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
