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? > xscanimage begans to work, but only with 100dpi, and the "Out of memory" > message do not occur any more.

You can do this at runtime by setting "export SANE_SG_BUFFERSIZE=262144". Or any other value. Bye, Henning
