mutex_enter with held simple_lock message while building system/kernel

Hi,

i just updated -current sources on my Dell Insipiron 2600
i386 laptop.
Since, i'm not able to build a new kernel anymore ...

The system drops into ddb with the following message:

mutex_enter with held simple_lock 0xc0d1a24c CPU0

This is a GENERIC+DIAGNOSTIC+LOCKDEBUG kernel.

I just updated source to 23 July (monday evening) and am
getting something
similar. My trace (below) also shows uvm_pageout() and
uvm_swapisfull() at
the bottom and is triggered when building a release..

kernel is basically GENERIC_LAPTOP+DIAGNOSTIC+LOCKDEBUG and
most unused
devices removed

iain

kernel: supervisor trap double fault, code=0

This one should be fixed, too.
