NetBSD armcurrent 1.5Y NetBSD 1.5Y (SHARK) #2: Sat Sep 29 18:03:25 CEST 2001     cato@armcurrent:/usr/local/tmp/nbsd010929/src/sys/arch/arm32/compile/SHARK arm32

My diskless shark (arm32) has not been able to boot successfully after
the change

   Module Name:    syssrc
   Committed By:   chs
   Date:           Fri Sep 21 08:02:56 UTC 2001

   Modified Files:
           syssrc/sys/kern: vfs_vnops.c
           syssrc/sys/miscfs/specfs: spec_vnops.c

   Log Message:
   use shared locks instead of exclusive for VOP_READ() and VOP_READDIR().

What happens is that it hangs at about the point where init runs getty.
Reverting the change above solves my problem.

(Sorry that I don't have more information, but I don't really know what
info would help... I'm happy to give more details if you tell me what I
should do.)
