Problem with MEDIAVISION PAS-16 SCSI CD-ROM

Post by Phil Ada » Sun, 23 Oct 1994 04:49:28



I am trying to install the Slackware version 2.0 off of CD-ROM. When I try
to boot using the bootdisk made using \bootdsk0\scsi I get the
response below. It looks like Linux is recognizing the scsi interface and
the CD-ROM but the system just hangs ( with drive A still spinning ).

I am using the MediaVision MV-1000 PAS-16 sound card with SCSI interface to
the CDR-H93MV CD-ROM ( does anybody know who really makes the CD-ROM? )

scsi0: at 0x388 irq 10 options CAN_QUEUE=32 CMD_PER_LUN=2 release=1
       generic options AUTOPROBE_IRQ AUTOSENSE PSEUDO DMA generic release=4
scsi0: PRO AudioSpectrum - 16 SCSI
scsi: 1 hosts.
      Vendor: MEDIAVIS     Model: CDR-H93MV Rev 1.32
      Type: CD-ROM         ANSI SCSI revision: 02
Detected scsi CD-ROM sr0 at scsi0, id 1, lun 0
scsi0: resetting for second half of retries  <---- here is where it hangs!

I have seen some other posts that reference the boot command:
  linux max_scsi_luns=1 pas16=0x388,255
Will this help in my case? Thanks in advance for any help on this problem!

     I recompiled my kernal after updating the scsi.c driver to add
     the info I got from a post a few days ago:

Edit /usr/src/linux/drivers/scsi/scsi.c
Search for a structure called blacklist and add the following line:
   {"MEDIAVIS","CDR-H93MV","1.31"},  /* Locks up if polled for lun != 0 *

Thanks to  Olav "Mac" Woelfelschneider for the original post!        

Hope this works.

best

All thats left to say is that this is now fixed since 1.1.62.

1. Anyone using Linux with PAS-16 SCSI and Chinon 535 CD-ROM??

I've been unsuccessful at trying to get Linux to work with my CD-ROM
drive.  The SCSI adapter is my Pro Audio Spectrum 16 sound card attatched
to an internal Chinon 535 CD-ROM drive.  This setup works fine under
MS-DOS and OS/2.  I've experimented with pl14 and pl15 kernels with no
success.  It always hangs at the same point:

scsi0: Pro Audio Spectrum-16 SCSI
scsi: 1 hosts.
  Vendor: CHINON  Model: CD-ROM CDS-535  Rev: Q14
  Type: CD-ROM  ANSI SCSI revision: 02
Detected SCSI CD-ROM sr0 at scsi0, id0, lun0
scsi0: resetting for second half of retries
scsi0: warning: SCSI command probably completed successfully before abortion

It hangs at this point, forcing me to switch back to a non-SCSI kernel.  
The frusterating part is that it does detect the PAS16 SCSI adapter AND
the Chinon CD-ROM!

Anyone have the same (or even similar) configuration?

Thanks in advance.
