I believe I have identified the problem, but it would be helpful if you could confirm the fix. Please apply the attached patch to a checkout of the src tree, then, compile and load the hwpmc module. There should be no need to build the kernel in its entirety, it is enough to do: # cd /path/to/freebsd-src # make -C sys/modules/hwpmc # make -C sys/modules/hwpmc install # kldload /boot/modules/hwpmc.ko -- You are receiving this mail because: You are the assignee for the bug.home | help
