So, the correct object pointer is 0xffffffff81281580, but vm_page has object = 0xfffffffb81281580. 0xffffffff81281580 0xfffffffb81281580 One bit flip (0x400000000). Either there is some HW issue or we've got some code that arbitrarily flips bits in vm_page_array (and perhaps beyond it). -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
