[Disksim-users] Why does controller_bus_ownership_grant problem happen?

[John Bucy]

Hmm ... that assert is new to me.  There may be some static
limitations on the number of devices per bus, etc -- I've never been
very familiar with that part of the code.  Please write back when you
figure it out so we know :)
