It works. But, of course, with a big lack of performance with 3D... So I prefer to put the nohz=off kernel parameter at boottime. If you search via Google, I'm not the only one : this problem occurs on many laptops, especially Toshiba (?) : http://sudan.ubuntuforums.com/showthread.php?t=779231&page=3 I didn't tried, but they explain that irqpool parameter is sufficient. SHoud I test it ? Can you explain me what these two parameters are doing ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't think nohz was enabled by default in older kernels.
