>Description:
I try to cross compile a netbsd 2 distribution on a linux amd64 machine (yes, shame on me :) ). I got the newest (2.0) sources via cvs up -dPAC -rnetbsd-2.
Building the toolchain works, but the kernel fails on sha2.c with
/tmp/ccUQgz9R.s: Assembler messages:
/tmp/ccUQgz9R.s:94: Error: bignum invalid
[lots of that]

*** Failed target:  sha2.o

*** Error code 1

If I remove crypto/cgd and ipsec from my kernel config everything builds  fine. As I do not really need this atm, this is no big problem for me.

>How-To-Repeat:
Checkout netbsd2, cross compile on a linux amd64 machine. You need
pseudo-device 	crypto		# opencrypto framework
pseudo-device	cgd		4	# cryptographic disk devices

Otherwise it will not compile sha2.c

Then build this kernel and it should fail.
>Fix:
None, sorry :(
