Dumping with /dev/null as a file crashes. Dumping to a normal file elsewhere works. Dumping through a redirect to /dev/null (tcsh) seems to work as well. /dev/null as a "file" works just fine w/o devfs. Eg: dump 0af - / > /dev/null - works dump 0af /usr/tmp/foo / - works dump 0af /dev/null / - SEGV w/devfs, works with normal /dev Anybody have some ideas? Does this happen only on alphas? ( I don't have a -current PC). FWIW, cat'ting the resulting /usr/tmp/foo to /dev/null works just dandy..
