It worked fine with 8.2, but using 9.0 (kernel 2.4.19-16mdk) it seems to take an age,
30minutes for a 20mb cd :-(
I have noticed that during burn the red light of the cd only comes of for short pulses
then it goes green, so it's not writing very often. When I first used it I aborted it after
a while as I didn't think it was working only to see that it had burned some of the cd,
but VERY VERY slowly.
I'm using an XP1500 with an ASUS A7V133 m/b with a clean install of 9.0 !
running cooker, I wonder? Download cdrecord from cooker in work and install it,
guess what, it works !
cdrecord-1.11-0.a37.1mdk
Looks like it's cdrecord !
It's nice to see it's not just me :-(Gregory K. Meyer wrote:I am reporting this here because the cooker kernel has not been updated since the release of 9.0, and I think this problem is kernel related.
In 8.2, I could burn a CDR at max speed (24x) on my Lite-On burner while doing lots of other stuff, never burned a coaster. CPU utilization was always minimal.
In 9.0, doing the same thing causes cpu cycles to go to almost 100%, cd burner never achieves top speed and I get lots of buffer underruns.
I have recompiled the cooker src.rpm for the latest cdrecord and the 8.2 src.rpm for cdrecord, so I don't think it is cdrecord. I get this same behavior no matter which version of cdrecord I use in 9.0. I experience the problem no matter how I invoke cdrecord.
If I run top while burning, lot's of stuff is using 5-6% of my cpu, but cdrecord tops out at 6% or so.
I have the ide-scsi modules loaded under 8.2 and 9.0 the same way. Under both versions, the burner is properly detected as /dev/scd0.
This seems to be kernel related. When I boot the vanilla linus 2.4.19 kernel, I don't expereince this problem. When I boot the 8.2 kernel, I don't experience this problem. If I boot the 2.4.19-16mdk kernel, as well as my 2.4.19-win4lin patched kernel, I experience the problem.
