[Bug 562832] Re: module drbd8 update kernel from 2.6.32-16 to 2.6.32-20

[crh]

The fix does not work on my freshly kickstarted ubuntu lucid server. The
result is the same, dkms complains that no kernel sources are installed
despite both generic and server headers are present.

The reason is that dkms tries to use the build link in
/lib/modules/2.6.32-21-generic (which does not exist) instead of the one
in /lib/modules/2.6.32-21-server (which does and correctly points to the
server headers).

The key to the whole issue is the use of uname -r (results in
...-generic) by dkms to determine where the kernel sources are. There
either needs to be a fix that creates the correct ...-server reference
out of 'uname -r' or a the kernel needs to be renamed ...-server so the
build reference does not have to be changed.

Adding a link /lib/modules/2.6.32-21-generic/build ->
/usr/src/2.6.32-21-server can serve as a workaround but is not a
sustainable solution.

The fix as provided does not work.

Bug description:
I have installed drbd8-utils on Ubuntu Lucid 10.04 beta 1.
 After updating the kernel to 2.6.32-20-generic, the module drbd can't be loaded.
I have an error during the load :

FATAL: Error inserting drbd (/lib/modules/2.6.32-20-generic/updates/dkms/drbd.ko): Invalid module format

Dmesg : 

[  190.376039] drbd: disagrees about version of symbol module_layout

When i update the kernel, i can just see in the log :

ubuntu-laptop dkms_autoinstaller: drbd8 (8.3.7): Installing module on kernel 2.6.32-20-generic.

I think that the problem results from dkms program
