ripping "enhanced" audio CDs

This has finally caused me enough grief that I'm going to ask about it and 
see if there's something I'm doing wrong or some nice solution to this 
really annyoing problem.

I'm on a 5-STABLE box, currently 5.5-PRERELEASE. I use cdparanoia and lame 
(via abcde) to rip my CDs to MP3. (This has happened to me with other 
rippers, like cdda2wav, IIRC, also.) Whenever I try to rip an "enhanced" 
CD that has one or more data tracks along with the audio tracks, it 
crashes the computer when it gets near the enhanced tracks. It has 
happened on a wide variety of CDs, all enhanced, and over a long 
period of time. It is very repeatable. Even if I ask the ripper to rip 
only the track prior to the enhanced track, it still crashes when it 
gets about 90-95% through the track. Even if I try to break out at that 
point, it still crashes the box.

I know has happened to me on both CD-ROM/RW drives and on my atapicam 
DVD+/-RW drive. I seem to remember it happening on 4-STABLE boxes too, 
with widely different hardware (different mobo makers, chipsets, etc.)

Does anyone know what causes this or what the fix is? Has anyone else had 
this problem and found a suitable workaround?

Right now the only workaround I've found is to start ripping the track, 
and let it crash the computer, then encode the track when it boots back 
up. Not a very happy workaround, as I have to fsck every time. :(

Any help or suggestions you can offer are greatly appreciated!
