	NetBSD 1.5ZD i386
>Description:
	On a SIS 85C01 with a "Quantum Designs 8580" IDE-controller, the kernel
	always panics with:

	extent_free: start 0x376, end 0x379
	panic: extent_free: region not found

	It happens in all kernels from 1.5.1 to 1.5ZD, but 1.5 works,
	so it must be something that was changed in pciide between
	1.5 and 1.5.1... (it works if I disable pciide).

	I can probably run a debug kernel on it, but I don't think I
	can save a crashdump for obvious reasons.
