netbsd-5-rcr uvm_fault

Hello list,

I am using an actual version of NetBSD 5.0_RC1 (amd). Today the kernel crashes with:

uvm_fault(0xffffffff80cae360, 0x0, 1) -> e
panic: fatal page faultkernel diagnostic assertion "vp->v_usecount == 1" failede

Any ideas what the problem could be?

Thank you for your efforts.
