while experimenting with lvm, I noticed that mlocking the vectors page at 0xbffff000 from user space causes an unresolvable page fault (see full trace below). In particular, the lvcreate process attempts to lock its mapped memory regions when activating a volume, which includes the vectors page.
Thanks for the report. I tried with the following:
#include <sys/mman.h> int main(void) { mlockall(MCL_CURRENT); return 0; }
at it just works for me. Does it also work in your setup?
