I just had a crash of FreeBSD 10.0 prerelease, svn revision 259409 (I believe).
I get this from a piece of paper, don't know how to get it from the OS
itself;
uname -a does not show svn revision, and I was unsuccessful building
devel/subversion from ports (successful from NetBSD-current amd64).
Times are in UTC. I was just successful doing a make buildworld
TARGET=i386:>>> World build completed on Mon Dec 16 06:43:43 UTC 2013
Maybe an instability in wireless rsu driver which currently provides my only
Internet access from FreeBSD on this computer, MSI Z77 MPOWER motherboard, where
re(4) driver fails to connect by Ethernet.
Following is from /var/log/messages, showing the crash and what happened shortly
before:
