If you have set CPUTYPE in /etc/src.conf such that your userland binaries are built with SSE, etc. then I expect most things to break because the FPU is in a funky state without this patch. I suspect if you don't set CPUTYPE so that your userland binaries do not use the FPU, you can probably resume just fine without this fix. > -a > > > On 3 March 2014 11:11, John Baldwin <[email protected]> wrote: > > On Friday, February 28, 2014 9:00:57 pm Adrian Chadd wrote: > >> On 28 February 2014 15:35, Adrian Chadd <[email protected]> wrote: > >> > ... how'd this ever work in the past then? > >> > > >> > >> .. and I've submitted it as a PR: > >> > >> kern/187152 > > > > Complete stab in the dark (not compile tested) here: > > > > http://www.FreeBSD.org/~jhb/patches/i386_fpu_suspend.patch > > > > -- > > John Baldwin > -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[email protected]"
