$ ldd /usr/bin/as
	libopcodes-2.18.0.20080103.so => /usr/lib/libopcodes-2.18.0.20080103.so (0xf7ec4000)
	libbfd-2.18.0.20080103.so => /usr/lib/libbfd-2.18.0.20080103.so (0xf7e14000)
	libc.so.6 => /lib/libc.so.6 (0xf7ca0000)
	/lib/ld-linux.so.2 (0xf7efc000)

The last kernel I know that don't have such problems is 2.6.31-rc6
May be I should bisect?
