Not the first time I see that backtrace, but I don't think it has
anything to do with the packaging, I'm beginning to think it might be an
incompatibility between the kernel modules in the older releases and
newer kernel versions..

Still, could you please attach the full system report with:

reportbug -N 831974

Kind regards,
