I can build it fine, and it even starts, but the plots area looks almost all black. The events and the tasks occurring on the "last CPU" (i.e., on CPU7 if I have 8 CPUs) are more or less fine, it seems (although still hard to work with, given the background). Actually, it's the last plot that "works". In fact, if I add a task plot, I do see what that one is supposed to show, but the events of CPU7 disappear. Others are there, because the marker moves if I click on the entries in the trace area... but they're kind of behind the black cover. A screenshot can be found here: http://xenbits.xen.org/people/dariof/kernelshark-v2-black.png Am I the only one? Can it be related to my configuration or build environment? I'm happy to help with more info or try some debugging, if you think it could be useful.
