As I said, wait for the next version - it won't be long. I am trying 3.9 now. It does seem to have fixed the /spu filesystem issue, and I no longer get kernel BUGs when SPU-using processes stop, but there is a new instability that is even worse as it locks up the system randomly. I feel like I should file a separate bug for the new instability. Unfortunately all I have to document it is a photo of the console; is that generally acceptable to provide, or should I transcribe it first? -- Rob Leslie r...@mars.org -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
