It's obvious now you say it ;-)
You are indeed right:
(kgdb) frame 9
#9=C2=A0 0xffffffff8067d3ee in uma_zalloc_arg (zone=3D0xffffff00bfed07e0, ud=
ata=3D0x0,

Now what does that mean??
I just experienced another panic, but it failed to writ to disk =20
:-(.=C2=A0 I will force another one and check that the details are the same.
