I've got a server that's been rock-solid under RH 9 for over a year. I just replaced the CD-ROM with a DVD-RW so that I could back up to DVD instead of tape. To get it working, I put 'hda=ide-scsi' at the end of the kernel line in grub.conf. Now the system is unstable and reboots when certain operations happen. So far it's rebooted when I tried to burn the dvd using mondoarchive and when I tried to run RealVNC. Note that a previous version of mondo worked fine with the tape and that VNC has been rock solid for the last year. The system is a dual-Xeon system with everything but the DVD burner being scsi. uname -a Linux orion 2.4.20-31.9smp #1 SMP Tue Apr 13 17:40:10 EDT 2004 i686 i686 i386 GNU/Linux /proc/scsi/scsi Attached devices: Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DDRS-34560D Rev: DC1B Type: Direct-Access ANSI SCSI revision: 02 Host: scsi2 Channel: 00 Id: 02 Lun: 00 Vendor: ARCHIVE Model: Python 04106-XXX Rev: 7230 Type: Sequential-Access ANSI SCSI revision: 02 Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: MegaRAID Model: LD0 RAID5 26241R Rev: GH67 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi3 Channel: 04 Id: 06 Lun: 00 Vendor: ESG-SHV Model: SCA HSBP M6 Rev: 0.61 Type: Processor ANSI SCSI revision: 02 Host: scsi4 Channel: 00 Id: 00 Lun: 00 Vendor: LITE-ON Model: DVDRW LDW-451S Rev: GSB6 Type: CD-ROM ANSI SCSI revision: 02 I don't see anything in /var/log/messages when the reboot happened. I'm guessing that it must have something to do with the ide-scsi emulation, but don't know where to go from here. Thanks!
