Bug Description
I'm unable to load the Ubuntu 11.04 Live CD (both 32 and 64 bit). The live CD for Ubuntu 10.10 works perfectly. When I boot off the 11.04 CD I get the purple screen that says Ubuntu and then I get a screen that says:
"Unable to find a medium containing a live file system".
It does not even get to the part where I can select to install or try it out. I checked the MD5 for the ISO and I also did an MD5 check on every file on the CD and it seems to be fine. I'm not looking to create a USB stick image, I simply want a 11.04 live CD just like the one from 10.10.

My DVD-RW drive (DVD-RW, SATA, Pioneer, AHCI mode) is not recognized with first three boot messages "failed to set xfermode (err_mask=0x4)" after an new installation of openSUSE 11.4. The problem did not appear for openSUSE 11.3. Workarounds from forums (Ubuntu) did not solve the problem, neither adding the "irqpoll" kernel boot parameter nor a hardware power off. For the second workaround only a first boot results in a recognized DVD drive. After rebooting the same problem appears as described above. The problem may be solved here "https:/ /bbs.archlinux. org/viewtopic. php?id= 107847", but i did not check this for my system.
Reproducible: Always
Steps to Reproduce:
1. (Re)boot system without hardware power off(e.g. un/replugging the power cable)
Actual Results:
DVD drive is not recognized, i.e. is not present in /dev, a CD/DVD cannot be read or written.
Expected Results:
DVD drive should be recognized.
The DVD-RW drive is a Pioneer DVR 216D SATA model. The "desktop" kernel is used.
