I also tried a v3.11 dev kernel, but that one failed to boot due to a nouveau bug. I did a bisect of the v3.11 dev kernel. The first run (so, half way) this bug still occurred. So I assumed the recession persisted. I use Gentoo with NetworkManager 0.9.6.4. I will try v3.11-rc4 as that boots again. Thanks for the suggestion. 2013/8/9 Larry Finger : > On 08/09/2013 04:25 PM, Ronald wrote: >> >> [ Please cc me as I'm not subscribed ] >> >> Mentioned commit causes a regression on my box.
