Yes, I have seen lots of posts about the DMA error but at that time
I didn't had those problems.

The DMA error could happen anywhere in a recording and I haven't
actually seen any artifacts since I immediately deleted the
recordings. The recordings that do not have the DMA error looks
OK, without any artifacts. Maybe not comes as a surprise...
The 2.6.18 kernel have not yet managed its way in to Debian testing
and I hesitate a little bit to do a forced upgrade.
Would the DMA problem be solved if I upgrade to 2.6.17 and 0.7?
