This problem seems to be brand &/or DMA speed specific for the DVD drive. I have an Asus DVD-E616P3 with firmware 1.06 that will freeze the system every time with audio CD's. When I swap it out for an old Pioneer DVD-500M or TSSTcorp DVD burner, I have no problems. The main difference is the Asus is DMA 100 which freezes, the Pioneer is DMA 66 which is good and the TSST drive is DMA 33 which is also good. Perhaps it has something to do with the transfer speed of the drives? An Optiarc SATA DVD burner in the same system works fine.

I also have another computer with a fresh Jaunty install with an Asus DVD-E616P2 with firmware 1.08 that will not mount audio cd's. At least it does not freeze the system. This drive is also DMA 100. A Plextor Px-716A Firmware 1.06 in the same machine that runs at DMA 66 accepts audio cd's just fine.

So, could it be something about brasero and PATA UDMA 100 optical drives?
