[oi-dev] Panic on using fuse with todays "pkg update"

[Stephan Althaus]

Hello!

I made a pkg update today, and was surprised to get a panic on using my 
fuse file system "exfat" on USB3, which i use for 1-2 years now.

Maybe some illumos patch is causing this (?)

I have build the exfat bits on the new BE, to no success..
