I had a super crash tonite!

I was trying to burn a DVD with growisofs, and everything froze, but the DVD light continued blinking. The HD light was still on too. I left it there, thinking it may just be X, but after an hour it was still the same! Nothing burnt! And I couldn't even turn off the power supply!!! O_o I had to disconnect the cable.

I was running Gentoo, kernel 2.6.10-r2, with firefox, gaim, fluxbox, engage and aterm also running there. I access the DVD with the SCSI emulation.

Since the DVD remained blank, I tried again, after reboot, with no processes. Same. This time, the power button was working though (maybe cos I didn't wait an hour?).

Finally, I boot into Debian 2.6.8, and I am happily burning the DVD with the same things running.


Any idea?

you should not use the scsi emulation with 2.6.10, but the native atapi stuff.

can you try with atapi ? and also see what is in syslog ?

Ok. strange i only had troubles with 2.6.8, but this was before it got fixed.

can you try debian's 2.6.10 please ? apt-get it from :

http://people.debian.org/~luther/powerpc/2.6.10-2/

Could you try disabling SCSI emulation (just unload the modules unless you compiled it into the kernel) and use the ATAPI driver (modprobe ide-cd)?
(cdrecord dev=ATAPI -scanbus)
SCSI emulation isn't exactly supported since cdrecord got the ATAPI driver.
Was this your first attempt at burning a DVD with Gentoo?

Ok. Thank you. I will try. Can I use the ATAPI driver with growisofs?

It was not the first attempt. I burnt some DVDs using the same procedure before, but with kernel 2.6.9

I experienced another problems that may be due to the SCSI driver. After playing a CD with gnome cdplayer, from an user account, the user was unable to access the DVD device from other applications, even after ejecting the CD and inserting it again.

By the way, is there any easy guide to set up UDEV? I have the udev, coldplug, etc installed. The daemon is up and running. I can access /sys ... Still, when I boot I get devfs as default. There's an option to unset devfs in a config file in /etc, but it says that when udev is active devfs will automatically be deactivated...

Maybe udev will also help with my /dev/dvd ...

Thank u!

I'm not sure, I've never used it.
emerge udev and either deactivate devfs in the kernel or pass "devfs=nomount" when you boot.
Hmm, not by default, /dev/dvd is not a standard entry. It's just a handful of stupid applications that seem to think so.

I read the udev guide at http://www.gentoo.org/doc/en/udev-guide.xml

Since the /dev is not selected by default in the pegasos sources, I guess I don't need devfs=nomount option... What I see at /dev I guess is what in that guide regard as:
^^; ... So I was using udev all the time... --u Sorry!
Still, I get a As in that guide suggests, and this other one, http://webpages.charter.net/decibelshel ... rimer.html
I tried creating the console nodes statically, although they already exist after boot... So I erased them, and created them again. I still get the same message. Basically, I don't see the activation of any service at boot... Not much of a problem, but I would like to see or [ok] or [fail] things ....

Growisofs works great without scsi emulation
Thank u!
