I've seen this happen after playing an audio cd with workman, then ejecting and inserting a new disk. H/w Asus dual PPro P65UP5 with an ncr53c810a scsi card (ncr53c8xx driver) and a Tosh XM-3701TA CD-ROM. Vanilla 2.1.105 SMP. Although the CD-ROM is on the ncr, there is also a 2940UW with two Quantum Atlas wide disks in this machine.
