Bug#758757: kfreebsd-10: d-i bugs caused by qemu-system-i386+smp
Using qemu-system-i386 with the -smp 2 flag, I started seeing weird
issues early in d-i: a boot-time generated file
/var/lib/cdebconf/templates.dat being incomplete, truncated and/or
corrupted; segfaults starting main-menu; or a hang with kernel message
"pid 97 (debconf): sigreturn eflags = 0x246".
I'm not sure it's actually a kernel issue, or just a Qemu bug. I think
it's unlikely anyone will run into it, but I do have some real SMP x86
hardware I could test this on if/when I get around to it.
