As of r261651 at CURRENT the driver works for me if: . disable multi-core at BIOS (so kern.smp.cpus: 1); . do not load driver at /boot/loader.conf (i.e. use the builtin kernel driver); . disable WITNESS* and INVARIANTS* (GENERIC does not work even with single CPU). -- WBR, Boris Samorodov (bsam) FreeBSD Committer, http://www.FreeBSD.org The Power To ServeReceived on Sun Feb 09 2014 - 15:56:34 UTC
