What I got was really odd situation that my newly installed kernel (and modules) didn't find the way to disk and loader complained about missing kernel on next boot. The /boot/kernel directory was simply missing and / filesystem dirty. Smells very similar to the problems with unclean shutdown (buffers not written out to disk) circulating in -current recently, but as I didn't have the serial console open while booting, can't say for sure. For the curious the procedure was as follows: checkout new sources buildworld/installworld build new kernel/install new kernel immediately do shutdown -r now repeat the last two steps as long as you wish or until the problem \ appears -- Vallo Kallaste To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
