My phenom is actually AMD Phenom(tm) II X4 965 Processor I know of one person, who sometimes posts on lkml, who also has a similar processor and now never goes beyond make -j4. My own A4, when it was alive, showed no problems (apart from only having two cores). My A10 (kaveri) is fine, and there I use make -j5 because it has an SSD. So, from my experience only the Phenom is a problem. OTOH, in many things they are slower than my SandyBridge i3, and in particular an SBU (single threaded) is much slower - some of that, but not all, might be because the acpi cpufreq governor works less well on AMD CPUs than the old K10 code did. > > As to the problem of the OP, is it possible that gcc was not complied > for the correct target such that in unusual circumstances it really > will attempt to execute an unsupported CPU instruction? > > If a reattempt is made to build atk (after cleaning the source tree) > does the exact same error occur at the same place?

But we don't know what CPU the OP was using. ĸen -- Il Porcupino Nil Sodomy Est!
