@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.
