After power-cycling things looked normal until WARNING: / was not properly dismounted warning: no time-of-day clock registered, system time will not be set accurately random: unblocking device. arc4random: no preloaded entropy cache arc4random: no preloaded entropy cache arc4random: no preloaded entropy cache pid 27 (sh), uid 0: exited on signal 12 May 28 14:29:07 init: /bin/sh on /etc/rc terminated abnormally, going to single user mode Enter full pathname of shell or RETURN for /bin/sh: pid 28 (sh), uid 0: exited on signal 12 May 28 14:29:10 init: single user shell terminated, restarting Enter full pathname of shell or RETURN for /bin/sh: I've tried the escape, tilda, control-b sequence, it's echoed but the debugger does not take over the console. The machine had been running stably under fairly high load for several days compiling www/epiphany. During the world build epiphany was run and it started segfaulting after a couple of minutes. Shortly after that the world build stopped. I was unable to see the error message, unfortunately. Thanks for reading, and any thoughts. bob prohaska
