cd burn pb with gnome on redhat



Hi,

I just want to share my experience on burning CD with gnome desktop on RedHat.

The RedHat is 7.3 with no patch at all.
I got a CDR Traxdata 12/10/32 firmware LSRA (/dev/hdc) and a DVD (/dev/hdd). Also I plug an Alcatel Speedtouch USB.

First I used the setting hdc=ide-scsi hdd=ide-scsi in grub config.
This had for effect to fail burning on the run or even not to be able to start the burn because of OPC failure (this thing which recognize the kind of layer on the CD-R).

To fix this pb, I disable the scsi emulation on DVD. I know that it removes the possibility of CD to CD copy but it is not my main usage.

Then I was disappointed by the real speed of the burning. I used Xcdroast and even if I set the speed to 12X, it was only 8X or even sometimes 4X. Moreover It happens that everythings crash. While burning, X crash, so I switch to console mode and after logged in, I got messages like "cannot fork" on a simple ls command. At this point, CDR is lost and I got to manually reboot.

Here is a log:

We could see somethi,g try to access continuously to /dev/cdrom (while it was burning). After, pppd is not able to re-init, then cannaserver crash and xinitd and X and gdm till the moment when no fork is possible.

I read somewhere that gnome was a little bit to agressive when it try to automount cdrom. So I simply kill magicdev.

There is no more automount but there is no more crash too, which is the most important, we are not on M$ win-shit. Moreover the speed is now OK, 12X asked on xcdroast gave 12X on real.
