Hi Bill,
Thanks for reporting this issue.
I have CC'ed the Debian linux maintainers as I noticed your kernel
reports a null pointer deference in the kernel (see below for the
trace). I have taken the liberty of reassigning it to the linux package
as well.
@linux maintainers: if you suspect that the null pointer issue is
unrelated to Bills boot problem, please clone the bug and throw the bug
back to upgrade-reports for further analysis.

Thanks,
