Package: dkms
Version: 3.0.12-4
Severity: important

Dear Maintainer,

dkms compresses some of the packages it builds. I guess this depends on the
kernel config that it builds for.
With xz compression, it compresses it in a way that's not compatible with
kernel's xz. The difference seems to be the CRC:

file kernel/drivers/misc/isl29020.ko.xz: XZ compressed data, checksum CRC32
# mainline driver, works
file updates/dkms/ddcci.ko.xz: XZ compressed data, checksum CRC64  # dkms
driver, fails to load

I assigned the severity important because it seems like new debian kernels (6.7
from experimental) have this compression on by default. If the situation
remains as it is but goes to the more stable debians it will break for most
users of dkms
