It seems that it is specific to bug or mutual incompatibility between some specific kernel and driver/firmware. Problem has appeared before in RHEL, Mint, Ubuntu and openSuSe, starting from about 2007. Some versions were free from it. I observed this problem after last upgrade, to version 3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013 (97c14ba) x86_64 x86_64 x86_64 GNU/Linux -- 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.
