Hey ed

Those errors look different to what was described (I only get one such
error in my dmesg), and different to what the OP reported (he didnt get
a cd0).

I don't run STABLE, just CURRENT, so I don't know what to suggest. There
was a lot of talk about problems burning in k3b on freebsd-stable@ a few
months ago, I suggest searching the archives for k3b and see what the
resolution was to that.

If you haven't already (and don't have a good reason to not), I'd ensure
your kernel + userland are up to date, perhaps track RELENG_6 rather
than RELENG_6_[12] and see if that helps.
