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 /local/src/NetBSD/src/sys/uvm/uvm_pdaemon.c:699

This is a GENERIC+DIAGNOSTIC+LOCKDEBUG kernel.
