The coolscan backend suffered from a very similar problem on SGI. The
workaround has been to limit the size of the data chunks read from the scanner
to 64K instead of 'sanei_scsi_max_request_size'.
Probably more a workaround than a fix but since there was no perceivable
performance penalty I kept it that way.
