The mobo's chipset is a VIA Apollo pro 133A (Southbridge: vt82c596b) The Plextor PX-116A when running as ide-scsi with **DMA on** cannot=20 mount disks (cds or dvds), cannot play dvd-movies and cannot readcd a=20 data-cd. When I disable the DMA, everything works ok. When I set it up as ide-cd, everything works ok no matter if the DMA is= =20 on or off. The drive is currently running at UDMA2 mode (ATA33). I replaced my old Delta 52X CD-ROM drive with this Plextor DVD-ROM=20 drive. The old Delta CD-ROM had no problem as ide-scsi with DMA on. (I want to say in other words that I wouldn't expect this to be a=20 hardware problem). I've pasted below the command output and kernel messages from the=20 following commands: cdrecord -scanbus mount=20 readcd=20 mplayer -dvd 1 Then, I'll paste output from: ver_linux /proc/cpuinfo /proc/modules /proc/ioports /proc/iomem lspci -vvv /proc/scsi/scsi cdrecord -scanbus doesn't produce any weird kernel messages. All the=20 other commands produce something like this: ide-scsi: The scsi wants to send us more data than expected - discardin= g=20 data ide-scsi: [[ 28 0 0 0 0 0 0 0 2 0 0 0 ] ] One last thing: I don't know if it's helpful, but I've read in the=20 cdfreaks.com forums that internally this Plextor DVD-ROM drive is=20 actually a Pioneer 120 DVD-ROM. Though, I cannot confirm this piece of=20 information. Any kind of enlightment on this matter or help would be welcome :) TIA =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D djart@blackmajesty:~$ cdrecord -scanbus Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J=CF=86rg Schi= lling Linux sg driver version: 3.1.25 Using libscg version 'schily-0.7' scsibus0: =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,0,0 =C2=A0 =C2=A0 0) 'PLEXTOR ' 'CD-R =C2= =A0 PX-W1210A' '1.10' Removable=20 CD-ROM =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,1,0 =C2=A0 =C2=A0 1) 'PLEXTOR ' 'DVD-ROM = PX-116A ' '1.00' Removable=20 CD-ROM =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,2,0 =C2=A0 =C2=A0 2) * =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,3,0 =C2=A0 =C2=A0 3) * =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,4,0 =C2=A0 =C2=A0 4) * =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,5,0 =C2=A0 =C2=A0 5) * =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,6,0 =C2=A0 =C2=A0 6) * =C2=A0 =C2=A0 =C2=A0 =C2=A0 0,7,0 =C2=A0 =C2=A0 7) * =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D djart@blackmajesty:~$ mount /cdrom/ mount: I could not determine the filesystem type, and none was specifie= d Kernel says: Aug 26 18:22:21 blackmajesty kernel: Attached scsi CD-ROM sr0 at scsi0,= =20 channel 0, id 0, lun 0 Aug 26 18:22:21 blackmajesty kernel: Attached scsi CD-ROM sr1 at scsi0,= =20 channel 0, id 1, lun 0 Aug 26 18:22:21 blackmajesty kernel: sr0: scsi3-mmc drive: 32x/32x=20 writer cd/rw xa/form2 cdda tray Aug 26 18:22:21 blackmajesty kernel: sr1: scsi3-mmc drive: 40x/48x cd/r= w=20 xa/form2 cdda tray Aug 26 18:22:22 blackmajesty kernel: ide-scsi: The scsi wants to send u= s=20 more data than expected - discarding data Aug 26 18:22:22 blackmajesty kernel: ide-scsi: [[ 28 0 0 0 0 0 0 0 2 0 = 0=20 0 ] Aug 26 18:22:22 blackmajesty kernel: ] Aug 26 18:22:22 blackmajesty kernel: ide-scsi: expected 4096 got 8192=20 limit 4096 Aug 26 18:22:22 blackmajesty kernel: ide-scsi: The scsi wants to send u= s=20 more data than expected - discarding data Aug 26 18:22:22 blackmajesty kernel: ide-scsi: [[ 28 0 0 0 0 2 0 0 8 0 = 0=20 0 ] Aug 26 18:22:22 blackmajesty kernel: ] Aug 26 18:22:22 blackmajesty kernel: ide-scsi: expected 16384 got 32768= =20 limit 16384 Aug 26 18:22:22 blackmajesty kernel: ide-scsi: The scsi wants to send u= s=20 more data than expected - discarding data Aug 26 18:22:22 blackmajesty kernel: ide-scsi: [[ 28 0 0 0 0 a 0 0 e 0 = 0=20 0 ] Aug 26 18:22:22 blackmajesty kernel: ] Aug 26 18:22:22 blackmajesty kernel: ide-scsi: expected 28672 got 57344= =20 limit 28672 Aug 26 18:22:22 blackmajesty kernel: ide-scsi: The scsi wants to send u= s=20 more data than expected - discarding data Aug 26 18:22:22 blackmajesty kernel: ide-scsi: [[ 28 0 0 0 0 18 0 0 1a = 0=20 0 0 ] Aug 26 18:22:22 blackmajesty kernel: ] Aug 26 18:22:22 blackmajesty kernel: ide-scsi: expected 53248 got 10649= 6=20 limit 53248 Aug 26 18:22:22 blackmajesty kernel: ide-scsi: The scsi wants to send u= s=20 more data than expected - discarding data Aug 26 18:22:22 blackmajesty kernel: ide-scsi: [[ 28 0 0 0 0 0 0 0 1 0 = 0=20 0 ] Aug 26 18:22:22 blackmajesty kernel: ] Aug 26 18:22:22 blackmajesty kernel: ide-scsi: expected 2048 got 4096=20 limit 2048 Aug 26 18:22:22 blackmajesty kernel: FAT: bogus logical sector size 0 Aug 26 18:22:22 blackmajesty kernel: VFS: Can't find a valid FAT=20 filesystem on dev 0b:01.
