I'm running 10-CURRENT amd64 on a Dell M6500. I ran into a strange issue when running `sysctl -a` in which my system would "freeze" -- the only interaction with the system which was registered was a press of the power button (which wouldn't actually initialize a shutdown). This is a big problem when /etc/rc.d/initrandom calls `sysctl -a` during system startup... I traced this behavior back to commit r240281 which added support for USB Dual Mode Drivers: http://svnweb.freebsd.org/base/head/sys/dev/usb/controller/usb_controller.c?r1=240281&r2=240280&pathrev=240281 At r240280, my system boots fine and I can run `sysctl -a` at will with no bad behavior. I haven't dug deeply into this issue, so this e-mail is more of a heads-up report in case anyone else runs into this issue. I'll add more debugging in my kernel config and capture the information from dmesg and others before and after the r240281 commit. Of course, any hints are appreciated as I delve into this. -Brandon
