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
