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:

qemu-system-ppc: ../hw/scsi/lsi53c895a.c:863: lsi_do_command: Assertion

Any idea what could it be and what could be done about it?
Wild guess is that this is because of the 'Already reselected' line
above. lsi_reselect() sets s->current, and later when lsi_do_command()
is called it gets confused because s->current is already set. But i
would need the whole logfile to see why this is going wrong, or even
better AmigaOS (which is not free as you already mentioned)
Thanks for looking at this. I've uploaded the full log here:
http://zero.eik.bme.hu/~balaton/qemu/aos-lsi-scsi.log.xz
but not sure you'd get more info from it as it seems to be working up to
the error. This happens short after boot when the driver is started which
seems to be going OK but when first accessing the device then it runs into
the error. I don't know how this controller works so can't really tell
what would be correct behaviour here.
