When I try to write a mini CD, cdrdao never stops
attempting to do its power calibration. There's no
problem for full-sized CDs, just the mini ones.

The process becomes unkillable -- kill -KILL won't stop
it, only a reboot. I suspect a bad interaction between
cdrdao and the kernel.

When I try to write the same mini CD on a different
DVD/CD RW on the same bus, I succeed without problems.
This may be because the 2nd drive successfully
indentifies the CD as 8X, while the first drive tries
to write at 32x. Given that I have to reboot the system
to recover, I haven't done a lot of experimentation.

I'm using 1.1.9 (Debian's current "unstable" version
from 2004-07). The kernel is 2.6.9 (also Debian). The
drives are an LG DVD-ROM/CDRW GCC-4320-B, 1.01 (the one
that thrashes forever) and a Samsung DVD+-RW/CDRW
TS-552B, TS04.
