Bug#310668: (kernel-image-2.6.8-2-686-smp: aha152x module hangs system when attempting to use scanner)

["Karl O. Pinc" <kop@meme.com>]

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.

Thanks.
