>Description:
First I compiled the kernel for FreeBSD 7.0 with

options         SCHED_4BSD

and the wpi-interface worked fine.

The compilation with

options         SCHED_ULE

caused the following error lines at dmesg-output:

wpi0: could not configure bluetooth coexistence
wpi0: wpi_cmd: cmd 16 not sent, busy
wpi0: could not configure
wpi0: could not send authentication request

The wpi-interface works fine after recompiling the kernel with

options         SCHED_4BSD

instead.
>How-To-Repeat:
Compile your FreeBSD 7.0 kernel with

options         SCHED_ULE
