The problem was that the code got its page-table from
current->active_mm. But these pointers are not set up during early boot,
so that the #VC handler can't walk the page-table and propagates a
page-fault every time. This loops forever.
Getting the page-table from CR3 instead works at all stages of the
systems runtime.
Regards,
Joerg
