If not (and perhaps even if it is), you may need to build a new initrd with mkinitrd. HTH, P.S. It's generally not recommended to put / on LVM since it can make recovery from disk failure difficult if not impossible. -- tim writer <tim-s/rLXaiAEBtBDgjK7y7TUQ at public.gmane.org> starnix inc. 905.771.0017 ext. 225 thornhill, ontario, canada http://www.starnix.com professional linux services & products -- The Toronto Linux Users Group.

I agree with JoeHill. When I was having constant crashes it was because my CPU was under-voltaged. Yet Windows XP kept running perfectly (if slower). I think Linux uses the hardware more fully, and is more effected by bad hardware. If you ever get a crash, try checking the /var/log/messages log for any kernel panics.

Hi John, Try using: cdrecord -scanbus and post the output. It should detect your writer and tell you the bus it is on. Also, you have to use the SCSI emulation for it by passing the following to the kernel (do this before the scanbus) where (x) is the IDE bus position of the drive: hd(x)=ide-scsi Try using XCDRoast as the burning tool. As far as burning DVD movies and stuff, I think you have to create an image of the video first using some special tools (similar to those used for SVCDs, and then burn them. I don't think XCDRoast cares about what you burn and what you burn it to, as long as you have a valid disk image to burn. Tell us what you find.

[OT] When will the persecution of MS *end*?!

Don't bother William; I have tried to have this discussion about 3 weeks ago and got nowhere. I am giving up on these people as far as politics and economics go. I you want to know, I agree with most of your points. I'll even add my own: - Failure to OFFICIALLY support Linux (As in their latest players, etc) If you want to keep trying to push this topic... good luck. I'll just predict that this is the climax of this discussion as far as intelligent arguments go. It's just that some people have such different concepts about life...

One might become suspicous of your hardware at this point. NetBSD was kinda jerky on my Duron due to some incompatibility between it and my HD controller. I think that it's NetBSD's fault, but what was really relevant is that it was downgrading to some PIO mode for HD access. That's a great way to make the computer very slow, and the mouse jerky.
