Hi I seem to have some unkillable Linux processes... This is on my AMD Ryzen, the exact same installation on my Broadwell laptop does not show this behavior. At the second top output, the three remaining processes' cpu usage is fluctuating, just as when they are running normally. Kernel is from one or two days ago with kib's patch that I got the other day. root@amd:~ # top PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 978 boinc 3 155 i31 129M 64M futex 3 0:52 100.74% wcgrid_zika_vina_7. 979 boinc 3 155 i31 112M 47M futex 2 0:56 99.24% wcgrid_oet1_vina_7. 980 boinc 2 155 i31 150M 87M CPU3 3 0:46 97.66% wcgrid_mip1_rosetta 977 boinc 3 155 i31 109M 43M futex 1 0:56 97.39% wcgrid_oet1_vina_7. root@amd:~ # service boinc-client stop Stopping boinc_client.
