Ok, I've just pulled (I now have a /bin/cdfs from 26th of March) however
I still get the same errors.

I have tried with a CD-RW and a DVD+RW.

cat /dev/sdC0/ctl gives me this:
inquiry HL-DT-STDVDRAM GSA-U10N 1.05
config 85C0 capabilities 0F00 dma 00550004 dmactl 00000000
part data 0 2141

ah and 'dmaon' had this displayed:
"disabling dma: not on a busmastering controller"
(I guess dmactl at 00000000 is in accordance with that?)

Thanks,
Mathieu.
