AFAIK there's no need to set the 8e partition type here. 83 will do.

^^^^^
Is that a typo in your config, or a cut & paste error?
Mind you, none of these things should really be causing a panic. But it would
be helpful for us to know if when you fix the typo, the problem disappears.
Likewise if that doesn't help, change the partition type from 8e to 83 and
see if that makes any difference. Let us know your results.
Cheers,
