If I start the amiga with auto boot I get a guru 8000 0004 error or boot loops. using the none autoboot firmware the system will boot to desktop.
However the system will become progressively unstable when using RTG modes. Having said that the system can idle without a problem, its only when I start opening programs/workbench windows problems start to become apparent.
At first its just a random Guru error every now and then (8000 0004, 8100 005, 8000 000A). Programs like iBrowser seems to trigger more guru errors, freezing or lock ups then anything else. but just opening workbench folders or scrolling a guide in multiview can also have the same outcome.
Over time system instability starts to be come so rampant that at it worst it the system would crash as soon as the desktop loaded.
I’ve tried fresh installs of workbench/drivers/Picasso96 but the outcome is all ways the same.
However if I just use the zz9900 as a scandoubler the system seems very stable. I’ve been using that way for over a fortnight and everything seems fine.
