There's a 5-second pause the first time negative segment offsets are
used, to provide a clear warning to the user. The softlockup watchdog
is supposed to kick in after 10 seconds, so something here is a bit
confused. It's probably that mdelay() is delaying more than a
second. It's a software delay loop which we really ought to replace
with something better (HYPERVISOR_poll is the obvious candidate).

The issue can be worked around by calling touch_softlockup_watchdog()
in the 5-second delay loop in arch/i386/kernel/fixup.c.

Thanks for the quick fix Keir!
