Random freezes, Radeon mentioned in the console

Question

I try to run Ubuntu 11.10. I tried :

• 64 bits release
• 32 bits release
• live CD

Ubuntu is freezing randomly... I don't know why. Mouse is freezing, screen go black then appear again, mouse is moving but I can't do anything.

Note : freeze can append if I run Firefox during install.

11.04 was perfect. I've never had such troubles...

I'm not a power user, just a fan... So I can't bring you informations. I just have:

• a classic SATA
  • disk 1 primary partition with Windows,
  • 1 logical with Ubuntu,
  • 1 primary with personal data.
• USB mouse.
• Ethernet cable.
• ATI RadeonHD card

When I use CTRL+ALT+F1 command, I have a lot of messages with errors. Radeon is repeated a lot of times.

Solution

I also faced a single instance after the upgrade where the freeze happened, but could not reproduce it. You may like to read this link https://wiki.ubuntu.com/X/Troubleshooting/Freeze. You can file a bug by providing more information about it to the developers.
