That may be the same thing that's happening with Ali's branch predictor

Quoting Nilay Vaish <[email protected]>:
Gabe, when I boot FS with O3 CPU and Ruby, I get the following output on
the terminal of the simulated system.
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 232k freed
init[1]: segfault at ffffffff802095c0 rip ffffffff802095c8 rsp

init[1]: segfault at ffffffff802095c0 rip ffffffff802095c8 rsp
00007fff38fa81b8 error 15
The segfault message keeps appearing. Do you know why this might be
happening?
Gabe, how can I confirm this? Is there something that I can do to resolve
the problem with branch prediction?
Thanks
Nilay
