This is an independent issue. Please file a separate bug for it.


This is dkms failing to build a module for an incompatible kernel.
Nothing can be done by the kernel to fix this as the kernel internal
interfaces are not stable, the module needs to be upgrade accordingly to
support the new interface.


This bug has nothing to do with dkms or the nvidia driver.
It's an incompatibility between linux-kbuild-6.3 6.3.11-1 and 
linux-headers-6.3.0-[01]-common{,-rt} (<< 6.3.11). The old header 
packages don't have asm/orc_header.h (that is available from 
linux-headers-6.3.0-2-common{,-rt}), but the scripts in the new 
linux-kbuild-6.3 generate code that includes the header, breaking the 
build of the any dkms module against the older headers. (This is the 
very first time I observed such breakage in the kernel header packages.)
Having this package combination installed (linux-kbuild-6.3 + 
linux-headers-6.3.0-1-common + linux-headers-6.3.0-2-common) is very 
likely for people tracking testing or sid.


Therefore please add Breaks against the incompatible headers.
Maybe even a NEWS entry would be appropriate to warn people upgrading 
from 6.3.0-1 to 6.3.0-2 that the headers for the older kernel are going 
to be removed and as a consequence all dkms modules will be removed for 
this old kernel, which may make the system unbootable into this old kernel.

No, this is modpost inserting a reference to a new header.  The
incompatibility is in our own packages.

On one of my machines, the upgrade was fine, but this is because the
NVIDIA kernel module wasn't rebuilt for the 6.3.0-1 kernel (despite
I have autoinstall_all_kernels="1" in /etc/dkms/framework.conf). So
I suppose that this bug would affect the machine only if the NVIDIA
packages are upgraded.

[resending, the previous attempt didn't have the bug in To/Cc]

This error can be easily be reproduced by installing
linux-headers-amd64 and dkms-test-dkms in sid.
Can be reproduced in testing by installing these packages
from testing and only linux-kbuild-6.3 from sid.

Another instance of this bug is the dkms autopkgtest regression on amd64:
https://ci.debian.net/data/autopkgtest/testing/amd64/d/dkms/35086312/log.gz

My suggestion is to add Breaks against these packages:

linux-headers-6.3.0-1-common (<< 6.3.11)
linux-headers-6.3.0-1-common-rt (<< 6.3.11)
linux-headers-6.3.0-0-common (<< 6.3.11)
linux-headers-6.3.0-0-common-rt (<< 6.3.11)

These can be removed for Linux 6.4, but maybe 6.4 needs
in linux-kbuild-6.4 similar Breaks against

linux-headers-6.4.0-0-common (<< $ver)
linux-headers-6.4.0-0-common-rt (<< $ver)

if a similar change as the one in 6.3.0-2 is yet to be
applied to 6.4.


This needs to be fixed before linux 6.3.0-2-* can migrate to testing,
otherwise it will break dkms module building for everyone still having
linux-headers-6.3.0-1-* installed (which is probably for the currently
running kernel).

as a workaround please downgrade linux-kbuild-6.3 to the version from 
testing (6.3.7-1)
