This is on 11.0-CURRENT, r261200. I saw it a few weeks ago, as well, but got busy and decided to wait for the snapshots and try again. On mine, it gets as far as this line, and waits a few tens of seconds: ustorage_fs0: <USB Mass Storage Interface> on usbus0 And then prints this: random: unblocking device. Followed by absolutely nothing until I reboot. On a WITNESS enabled kernel, it then proceeds to warn me about WITNESS and performance, before going on to mount the root file system, and bring up user space: WARNING: WITNESS option enabled, expect reduced performance. Trying to mount root from ufs:/dev/mmcsd0s2a [rw,noatime]... Curiously, it looks like the non-WITNESS kernel is also not finding the onboard MMC, so that might be relevant. In my case, I don't actually use it, so if it doesn't see it, it's not an issue for me Anyone know what I'm not doing right ? I -thought- all I had to do to turn WITNESS off was comment out the options line in my conf file, and I'm sure it worked on the BBW a year or so back. I've attached the two dmesg outputs as well as the conf used, but as I say, it's stock, with the exception of WITNESS being turned off. Iain PS, About a year ago, we mentioned IEEE1588 and the cpsw driver, a quick grep through /usr/src/sys showed the following drivers had the "IEEE1588" string in them: e1000 (/dev/e1000/*.h) IXGBE (/dev/ixgbe/*) NLM (/dev/mipd/nlm/board.[cv] No idea how functional each one is, but if anyone was thinking about adding 1588 support to the cpsw, might be useful - Unfortunately it's a little beyond my skillset --------------090600090001030802010901 Content-Type: text/plain; charset=UTF-8; name="BEAGLEBONE-TARDIS.kernconf.txt" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="BEAGLEBONE-TARDIS.kernconf.txt" # BEAGLEBONE -- Custom configuration for the BeagleBone ARM development # platforms, check out http://www.beagleboard.org/bone and # http://www.beagleboard.org/black.
