No luck with the mentioned 2.6.32 kernel, so I removed it and went back
to my previous kernel. I started playing with Brasero and K3b and K3b
magically decided to work. I still get the dmesg I/O errors, but it's
still burning.
[ 527.482723] sr 0:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRI
I've also run into this problem. I first experienced it a few days ago
and it magically fixed itself. I burned about 3 or 4 DVDs since
Wednesday night when it just started working on its own until now, where
I'm having the same problem again and it's not going away.
I'm going to try the 2.6.32 ker
