lsi53c895a assert with AmigaOS

[BALATON Zoltan]

Hello,

AmigaOS4 also has a driver for this card so I've tried to test it but it 
trips an assert. Does anybody have an idea why and how it could be fixed? 
Sven's recent patches don't seem to have an effect on this, it still 
happens shortly after it tries to access the SCSI device with those 
patches applied. (Unfortunately AmigaOS is not freely available so it's a 
bit hard to reproduce but I can do tests if needed.) I got the following 
traces:

Any idea what could it be and what could be done about it?
