I am using the cdrecord from Slackware 8.1 (or maybe it is the cdread 
from Slackware 8.1 - I needed something newer to deal with encrypted music 
CDs).  They work with kernel 2.2.16 and my 2.4.31 sm kernel, for me.

Try my sm and my 2.2.26 my sb kernel for burning CDs (not USB). If those 
work, I will add whatever they have that l8 might be missing for burning 
CDs.

I know very little about CD burning, just what I learned from you.  What 
is /dev/pg0?  Ask on the list for more help and then I will be happy to 
modify my l8 kernel to add more modules or whatever it needs.

Built into the l8 kernel, I think.  Try without this module and just 
insert the following ones.  If it needs the module, you will not be able 
to mount CDs without it.  Sometimes inserting a module when it is already
in the kernel causes a crash.

These should all be supported in l8 kernel.

I do not insmod loop to burn CDs, just to mount a loop filesystem.

Compare the config for that with my l8, in the areas of the above modules.

Does David's 2.4.31 kernel work to burn CDs?  Use HIS modules, not mine, 
they are not interchangeable because he compiled using a different glibc.

We will figure this out eventually.
I have to do a few other things first today.
