Hum, well, they were on the same channel and they both had burn-proof enabled.
The interesting thing about burning them was that if one CD finished burning
before the other did, then cdrecord couldn't seem to issue the eject command
until the IDE bus was free. Thus, they would both eject at the same time. This
tells me that either (a) the SCSI Generic implementation on Linux is not able to
handle multitasking SCSI emmulation or (b) my Promise IDE controler doesn't
handle it. Either way, if you're going to be using linux for this CD burning
machine, I'd go with either CD burners on seperate IDE channels or a SCSI
implemenation (which would be more expensive).
