I had the same problem (thinkpad R40, radeon mob. 7500, gutsy with all updates, radeon driver) I am not using the fglrx driver which was implied as the culprit in some other very similar bug reports. I used the old Kernel from feisty for a while and that worked just fine for suspend, except that it broke a few other things (most notably atumounting usb-storage).
After reading this post I installed the hardy kernel and everything now works as expexted. -- [Gutsy]Suspend-to-disk (hibernate) and suspend-to-ram do not work anymore https://bugs.launchpad.net/bugs/156113 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
