NetBSD 9.0 randomly boots

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I have upgraded my 8.1 to 9.0 from sources. Kernel seems to be stable,
but only if it can boot ! My CVS tree was upgraded last sunday (14:12:38
CET) and my kernel is customized as I need ALTQ.

	Sometimes, kernel cannot allocate ressources and panics, or loops in
configure stage. But the same kernel can also boot as expected, and when
it boots wihtout error, it runs fine. Of course, old kernel always boots
on the same hardware.

	My configuration :
