I just picked up Turbo Silver and a 2091 controller for my 2500/20 this
weekend, and it exhibits the same problems, so it is not specific to the
2091 and 2630.  BTW, Turbo did run properly on my 2500 before installing
the 2091 (I was using the 2090A controller).

This seems logical, since the GURU reported when Turbo crashes is an
address error, with an address of 00000000 as the offending location.
This is repeatable in both 68020 and 68000 modes, whether the system is
booted from the hard disk or an unmodified Workbench floppy.

Is it possible that this will become a 'non-problem' when Commodore
upgrades the 2091 ROMs?  My dealer told me that there is a ROM upgrade
due out in about a month.  Please note that this was the first I had
heard about any upgrade, so it may be misinformation.
