Date: Fri, 17 Jul 1998 10:49:29 +0200 From: Stephane KLEIN <stef@dalim.de> To: linux-scsi@vger.rutgers.edu This is a multi-part message in MIME format. --------------FDA66A8050C0BEC78613F8A5 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hi, I am trying to use an Agfa ( Studioscan ) flat bed scanner on my linux box with a UNIX driver that work fine on lots of different UNIX's ( IRIX 5.x, 6.x, Sunos, Solaris, HP-UX ... ) In order to do that I have created a new generic scsi device driver that allows me to send my scsi commands the same way as with other UNIX box. This device driver mostly takes 90% of "sg.c"'s code and only modify the way the scsi commands are sent ( ioctl structure instead of using read and write with sg ). I am now able to send my scsi commands through my device driver but some scsi command causes a "general protection: 0000" error while waiting in "interruptible_sleep_on" after calling "scsi_do_cmd". I don't know why some commands are working and some are not and I also don't know how to interpret the syslog messages: Thanks in advance for any help.
