CONFIG_LATENCY_TIMING=y

I'm betting this is the same thing I'm seeing. Are you running on a
uniprocessor x86_64? And if so are you seeing messages similar to the
following?

init[1]: segfault at ffffffff8010fadc rip ffffffff8010fadc rsp
00007fffffdacfc8

If so, then I suspect that you're getting a segfault in ld.so (at least
that's the furthest I've gotten so far). Something about how the kernel
sets up the memory map is upsetting dynamically loaded executables. I
can boot with init=/sbin/sash, but when I try and run a dynamically
linked program, I get segfaults.

You might try turning off LATENCY_TRACING and see if that allows you to
boot and run (works for me).

Meanwhile, I'm going to try and pin this down to something better than
"somewhere in ld.so..."

hi,
actually i'm running on a dual processor x86_64. with the problem i was having, i never got far enough to see the message you asked about. Steven Rostedt's suggestion to turn off NUMA worked and i am now able to boot. However, if I turn LATENCY_TRACING on, i get an immediate reboot after the kernel is uncompressed. this doesn't sound like the same problem you're having, though.
