@Simon, i'm usibng a Acer Apire One 722 (about video card, lspci says: "00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Wrestler [Radeon HD 6290]").
syslog says: Oct 14 21:19:16 pangoo kernel: [ 37.914704] [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD) Oct 14 21:19:16 pangoo kernel: [ 37.914715] [drm:evergreen_resume] *ERROR* evergreen startup failed on resume I'm not sure if it replies to ping or ssh, but after the blank screen I can hear the login screen sound, so I guess the PC is still working. I can experience the blank screen more or less once every two reboot. It started after kernel upgrade to 3.2.0-31. Yesterday I upgraded to -32 but it didn't solve. Now I've setup the 3.2.0-30 as default kernel on grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058303 Title: linux-image-3.2.0-31-generic-pae radeon regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1058303/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
