-current kernels since somewhere between June 10th and July 11th panicright after detecting mySCSI CD-ROM drive - assertion in sys/kern/kern_synch.c, line 192. Bootsjust fine when there isa CD in the drive or the drive tray is open. Some sort of a timing issueor a race?

The machine is an i386 (Intel mobo, Pentium III). The SCSI system consistsof two qla1040 cards,single-ended and differential. The SE card has two (ancient) SCSI harddrives and a Plextor CD-ROM.
