>Description:
If I try to kldload bktr, the kldload process gets stuck in state swwrt and exercises the disk
(it doesn't seem to fill the disk though). Only the first line of the detected devices show
up in the kernel log. Here the boot-dmesg and the output after kldloading:

=================================
bktr_mem: memory holder loaded
bktr0: <BrookTree 878> mem 0xf7002000-0xf7002fff irq 11 at device 12.0 on pci0
However, the remaining lines make it into the log when shutting down the machine!
The bktr deviceo is not usable in this state.
>How-To-Repeat:
On this particular machine 100% reliably reproducible. Just kldload bktr_mem and
then bktr.
>Fix:
Build bktr into the kernel.
