** Description changed: With ums (nomodeset kernel parameter) this laptop suspends to ram just fine. However ums seems deprecated nowadays and we don't have direct rendering anymore: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/946677 With the default kms, during resume from suspend I'm getting: [drm:r100_ring_test] *ERROR* radeon: ring test failed (scratch(0x15E4)=0xCAFEDEAD) [drm:r100_cp_init] *ERROR* radeon: cp isn't working (-22). afterwards the log and VTs are flooded with [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(4). [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. + --- + 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: ** Attachment added: "ProcEnviron.txt" https://bugs.launchpad.net/bugs/1029159/+attachment/3248075/+files/ProcEnviron.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029159 Title: 1002:5975 kms radeon drm: suspend freezes graphics, hibernate reinits ok To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1029159/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
