--nextPart4962687.lb3GUAW8lM Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Subject line is the executive summary of my problem: I have a box with an Intel 945GC A2 chipset that will not poweroff on shutd= own=20 if the usb kernel module is loaded (or statically compiled into the kernel)= =2E=20 Unloading the usb kernel modules sometime during shutdown (I hacked the usb= d=20 rc script for this) to work around the problem helped until I needed to hoo= k=20 up another device which uses ucom(4) to the machine. On kldunload, ucom=20 claims to detach, but remains loaded and subsequent kldunload attempts=20 trigger the error "kldunload: attempt to unload file that was loaded by the= =20 kernel". The stuck ucom in turn prevents usb from getting unloaded and the= =20 machine cannot poweroff. I have already tried disabling EHCI, but it does not help. Any ideas on eit= her=20 getting uhci to properly detach on shutdown or getting rid of ucom?
