>Description:
When using a kernel with minimal compiled in modules (i.e. only the bare
minimum) and loading cam(4) and usb(4) during the boot time then:
If a usb-mass storage device (da0) is inserted:
- on shutdown (`shutdown -p now`) the usb controllers fail to shutdown and the
computer is not powered off
- if the usb-device is removed the kernel spams the console with:
"""
xptioctl: pass driver is not in the kernel
xptioctl: put "device pass" in your kernel config file
"""
even though cam(4) is still loaded by the kernel and the pass device was
locatable on first connection
- thereafter no usb-mass storage devices are recognised by the computer
>How-To-Repeat:
Compile computer with attached kernel config, load the appropriate drivers from
loader.conf and rc.conf:
<file name="loader.conf">
ahci_load="YES"
</file>
<file name=rc.conf">
kld_list="random pty firmware agp ehci xhci usb"
</file>
the insert usb-mass storage device (flash), and remove. Observe above
conditions.
