That does help indeed.

When I'm using rumpdisk I'm still observing crashes, however, more
precisely:

Kernel General protection trap, eip 0xffffffff81011eee
kernel: General protection (13), code=2000
Stopped at  0xffffffff81011eee: mov     %ax,%es
0xffffffff81011eee(ffffffffbfbd4618,ffffffffbfff5230,ffffffffbe396d50,ffffffffbe396d90,ffffffff8103705b)

That's:

ffffffff81011ee9 t _kret_popl_fs
ffffffff81011ee9 t _kret_popl_gs
ffffffff81011eed t _kret_popl_es
   0xffffffff81011eed <+0>:     pop    %rax
   0xffffffff81011eee <+1>:     mov    %eax,%es
ffffffff81011ef0 t _kret_popl_ds
ffffffff81011f12 t _kret_iret
