* Ok things are broken here. If we lower the spl level to SPL_SOFT
* then, for the most things work. However wd interrupts start to get
* lost ... i.e. you either get wdc interrupt lost messages or
* wdc timeout messages.
* The fault is the CLKF_FRAME macro uses in kern_clock.c. This
* currently always returns 1 thus splsoftclock() is always
* called before calling softclock().
*
* This is about to be fixed
