Hm, if you could give me some hands-on? How do I do that? > Did you rebuilt the world after the update ? It should work both ways, > but knowing the answer trims half of the change for suspect. I built world and kernel in a clean env. rm -rf the obj part. The whole boot is done via nfs. I do boot the tree via netboot, crossbuilt on amd64. The machine is shot I can not boot from disk atm. With the r320421, the picture is the same, as expected. > Can you run the ktrace tests on ppc ? > cd tests/sys/kqueue/libkqueue/ > make > ./kqtest This is chicken and egg, my src is on the nfs drive :( I'll check-out a src tree on this machine tomorrow and do test build/run. Thx for the feedback! Andreas
