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