No it's a frontend and a slave backend, i.e. I'm using the 350 for recording. > My board has *only* the PVR350, a 160G hard disk, a USB wireless key > and a slim CDROM which I almost never use.

But, I have a stable 350 in a Epia-M 10k board and so do others. I used to have a 80GB hard drive in this box and it ran stable for about six months (I guess the total power draw was just about managable for my 90W supply). So I don't think that bug is the showstopper you think it is. Of course I could be wrong. > I am also seeing a lot of DMA errors in the logs.

I did try disabling DMA on the hard drive and it didn't solve my lockup problem.
