I'm getting this hangup with 4.5 in aranym:

I assume that this has something to do with the ncr5380 updates.
It also has to do with the assumption that aranym is the same as an atari.
Aranym doesn't actually implement a 5380 device. Instead it attempts to
fool the operating system that runs on it. Presumably this is done to
avoid having to modify existing operating systems.
Does Geert's "initcall_blacklist=atari_scsi_driver_init" workaround help?
