xenoson, thank you for clarifying. Did this problem occur in a Ubuntu release prior to Precise?

[drm:radeon_cs_ioctl] *ERROR* Failed to schedule IB ! The graphic is frozen but looks intact and the mouse pointer moves. It's possible to change to VTs. From this state, a reboot hangs somewhere down the line shortly after the plymouth splash appears and looks normal. Interestingly this can be rescued by pm-hibernate from the console. After waking up from hibernate the X session continues as if nothing went wrong in between. I tried with 3.4.0-030400-generic-pae from kernel-ppa/mainline, it doesn't flood the logs anymore but the first two errors and the frozen graphic is the same. - Attached is the syslog of a hibernate suspend hibernate cycle and lspci -vvvxxxx before, during and after. - --- + Attached is the syslog of a hibernate suspend hibernate cycle and lspci + -vvvxxxx before, during and after. + + WORKAROUND: With ums (nomodeset kernel parameter) this laptop suspends + to ram just fine. + + --- ApportVersion: 2.0.1-0ubuntu11 Architecture: i386 DistroRelease: Ubuntu 12.04 Package: linux (not installed) Tags: precise Uname: Linux 3.5.0-030500-generic i686 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: - --- + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
