That limits the buffersize to 32768 bytes. However, the avision
backend does ignore the buffer size in the calibration function, so
I'm a bit surprised that this works. Maybe the kernel upgrade changed
the behaviour and not this option?

Try setting the buffer size to bigger values again. You can do this at
runtime by setting "export SANE_SG_BUFFERSIZE=262144". Or any other
value.
