RE: [Xen-devel] PaX Security w/ Kernel.org DomU 2.6.31.7
I've put some xen_raw_printk statements in xen_setup_kernel_pagetable, and I'm
not seeing the output on the console, even when I use on_crash = 'preserve'.
So the crash may be happening sooner than that. I've also enabled domU crash
dumps in xend, but when this crash occurs, the core file is 0 bytes and labeled
'-incomplete'. Could the crash be happening too early to get a core dump?
Also, is there anything like ksymoops which I can use to interpret the stack
trace and find the function where the crash is occurring?
Thanks,
John A.
