LOL. I have a phenom x4 : from time to time (fairly frequently) it loses its lunch during compiles if I use make -j4. On less-frequent occasions it does the same even with make -j1. And always memtest86+-5.01 is happy [ well, if I use the "run all CPUs [F2] option it locks up, but it does that on at least two other mobos too: one of those is an intel SandyBridge so that issue is not AMD-specific ]. > Additionally i can boot Knoppix 6.7 with kernel 3.0.4 and it is running stable. > But when i boot Knoppix 7.2 with kernel 3.9.6 the system is freezing! > Aditionally i tried out kernel 4.3.0 in Debian but it does not help.

I suggest that you begin with standard 3.2.latest (just in case you turned out to rely on something in the debian kernel but not upstream). Then try 3.9.latest : if that runs ok, continue with 3.16.latest. If not, try e.g. 3.4.latest. The aim is to first find which minor release broke, and then which update in that series broke it. What you *might* need to do is also try .0 versions of each of these. I am suggesting that you bisect this. Bisection is usually a pain, so I suggest that you first find a working version, and then work through the next stable release of that version to find which commit broke it. I suspect I might have phrased my suggestions badly, but even 3.9 is so long ago that most of us have forgotten about it [ my last box running a 3.10 LTS kernel was a ppc64, and I have not booted that for about 2 years ]. Good Luck, and I hope you get a better suggestion. ĸen -- This email was written using 100% recycled letters.
