Hi Ohta,
I've decided to wait until I have access to my own card with upd64083 and upd64031a devices. I'll be back in the Netherlands in about two weeks from now, and then I can pick it up and bring it back with me to Oslo where I can test it and fix the problem.
The backtrace doesn't really help me, I think I need to do a bit of debugging myself.
A bit of a shame that I didn't bring it with me a week ago. It was on my list of things to take with me, but my suitcase was already pretty full so I decided against it. Next time I'll make sure I have it :-)
For now just use your workaround. It can't do any harm, but it is not the right solution. That will have to wait until I can test it myself.
Regards,
Hans
