Hey guys,
I noticed this nasty kernel NULL pointer dereference yesterday on
6.7.2-arch1-1 (haven't done this in a while) but also today, after
updating to 6.7.3-arch1-1 it's still there, so dumping the panic here.
Hopefully it'll be resolved by 6.7.4-arch1-1.
The thunderbolt gbit adapter always worked in the past, so this seems
like a regression. Anyway, here's the log.
