Hi,

I got a loaner G5 with an NVMe drive, but I haven't been able to replicate the
crash you're seeing. However, I think that's probably because I'm only reading
from the NVMe since it's NTFS formatted and I didn't want to trash someone
else's files. I'm waiting for a new NVMe drive to arrive so I can do some
destructive testing which should hopefully replicate the bug.

In the meanwhile, can you try the patch above? That seems to fix bug which is
causing MSIs to be unusable. I'm not 100% sure why that woudld matter, but it's
possible the crashes are due to some other bug which doesn't appear when MSIs
are in use.
