 If this is a bug in NetBSD, it's also a bug on this Linux:
 
 Linux eternium 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u4 (2015-09-19) x86_64 GNU/Linux
 
 on a:
 
 model name	: Intel(R) Core(TM)2 Duo CPU     E8600  @ 3.33GHz
 
 CPU.
 
 Nothing I see says that OSXSAVE implies that AVX instructions are
 implemented and working.  According to:
 
 https://software.intel.com/en-us/blogs/2011/04/14/is-avx-enabled/
 
 the AVX flag (bit 28) also needs to be asserted.
