I can reproduce on both my build machine (8 core) and my laptop (4 core). If it helps I can share the rootfs. On my laptop I was able to reproduce within 5 minutes. 1. make defconfig ARCH=um 2. make -j 4 linux ARCH=um 3. ./linux ubda=../Downloads/Debian-Squeeze-AMD64-root_fs mem=1G 4. login to tty0 5. wait a few minutes 6. try to run top, it will hang in nanosleep Thanks, //richard ------------------------------------------------------------------------------ _______________________________________________ User-mode-linux-devel mailing list User-mode-linux-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel
