I have installed RH9 on a system which has SCSI RAID disks and a SCSI tape drive but an IDE CD- ROM drive. When I attempt to mount a cd-rom by the command mount /dev/cdrom /mnt/cdrom the system waits a few seconds, displays the message hda: (_ide_dma_test_irq) called while not waiting and reboots itself. I have run RH9 on all-IDE systems and on all-SCSI systems (including the CD-ROM drive) with no such problem. Any ideas out there? Thanks in advance, H. D.
