[Xen-devel] writable page tables appear to be causing xen to lock up

[Kip Macy <kip.macy@xxxxxxxxx>]

I've just tried enabling writable page tables in FreeBSD.

I'm seeing the following code in traps.c hit over again. Disabling the
DPRINTK on line 341 doesn't help, it just causes the machine to become
unresponsive quietly.


xen_fault:      

if ( likely((fixup = search_exception_table(regs->eip)) != 0) )     {
        perfc_incrc(copy_user_faults);         
        if ( !shadow_mode_enabled(d) )
            DPRINTK("Page fault: %p -> %p\n", regs->eip, fixup);
        regs->eip = fixup;         
        return 0;
    }
