https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217994 --- Comment #14 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Sylvain Garrigues from comment #13) Thanks! I suspect that the problem is with BEXTR instruction that is available on Haswell, but does not seem to provided by (at least some) EC2 instances. Not sure if it requires any support from the hypervisor or if it's a problem with underlying hardware not supporting the instruction. So, I bet on your guess from comment #9. -- You are receiving this mail because: You are the assignee for the bug.
