He is not affected by the timer interrupt problem mentioned above, so he is fine with this kernel. Ah yes, and things still work, also after suspend.

After last resume (with kernel 3.10.2), still the same problem. RC6 is _not_entered and temperature is at high peak. -- 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.
