System: NetBSD pip 1.5ZB NetBSD 1.5ZB (PIP) #0: current after 20020310 (last check with 20020317-100000UTC)
Architecture: i386
Machine: i386
>Description:
	kernels built after around 20020310 fail to survive rc phase of startup.
	Panics (bad trap) occur mainly in malloc code
	happend with custom and GENERIC kernels
>How-To-Repeat:
	build kernel from current and try to boot into multi user with
	new kernel 8-(
	Example (using GENERIC_ISDN)
	DDB: (beware hand copy - as savecore from alternate device wont - see other PR)
	uvm_fault(0xe3819468, 0, 0, 1) -> e
	kernel: page fault trap, code=0
	stopped in pid 120 (sh) at malloc + 0x24d: 0(%esi),%eax

>Fix:
	? - i did see changes in subr_pool.c and alike around that time - seems close
