Including Compaq (now, I guess, Hewlett Pacquard).

In particular, the code sends a FLUSH_CACHE ATAPI command to CD drives 
to make sure that packet-writing burner software operates properly. The 
broken LG firmware interprets that standard ATAPI command to mean 
UPDATE_FIRMWARE, and you can imagine the results. Mandrake kernels from 
-21mdk will take care to not flush any LG readers.

If they want a specific problem, tell them that it died because the 
firmware violated the ATAPI specification and gutted itself as a 
consequence, and that "it's a known problem" (magic phrase, that).

Cheers; Leon
