From what I've read on Slashdot the problem is related to a CD-ROM flush cache command that sets off the drive to destroy it's firmware. The reason it's surfaced now is because of some new features in the latest kernel.
"The current news is that it was triggered by the addition of packet-writing code to the 2.4.22-rc2q5 kernel on Aug. 15, no news on how that determination was made. One must suspect that querying the drive for the format of the disk or its capabilities somehow triggers a firmware self-destruct bug in the CRD-84xx models."
This might cause some headaches. LG say they don't support Linux (which is a lie) and want to limit any possible claims made against them, and Mandrake customers are going to want compensation.
I have here a brand new LG DVD-ROM drive GDR-8161B and on the box it says:-
