I've removed the yahama cd drive from the aha1524 scsi chain, so now the only device on the bus is the scanner. I now have to "modprobe sg" before the modprobe that loads the aha152x driver, but otherwise behavior is as before. (The scsi chain was and is terminated btw. Is now terminated interally on the scanner, it was terminated with an external terminator on the cd.)
Ran vmstat after trying to scan before the hang. It showed virtually no system activity, AFIK, 1% cpu, no disk, although I didn't look at the memory statstics. It _seemed_ that vmstat hung before the mouse hung, but that could just be me. Based on the number of lines vmstat printed it took about 120 seconds to hang after pressing the xsane preview button.
