Well, the question is, "what is the problem"?
Your problem is that a debug message is being output by the kernel and filling your logs. If the debug message doesn't do anybody any good (and it doesn't) then removing the debug message is a fine way of solving the problem.
I looked at _why_ the debug message was being generated in this particular case a long time ago, and it seemed to essentially be a bug in the IDE code, but other than generating the debug message, basically a harmless one, and there was no interest in fixing it among the kernel people I talked to at the time.
(I don't remember details any more; it was several years ago.)

*This* problem is certainly not a buggy CD-ROM. There are other (rarer) problems with logs filling with magicdev that do have to do with buggy CD-ROM drives; so that is perhaps what you heard about.
(Most common one is that some Yamaha CD-RW's apparently report media in the drive when they don't have any media in the drive. magicdev tries to mount it, and that failure generates an error message.)

Are you sure that the LED flashing isn't the debug messages being written to your hard drive?
