[Bug 1535307] Re: running 'rr' make check causes kernel "hard LOCKUP"
I tested with linux-headers-4.4.0-040400 / linux-
headers-4.4.0-040400-generic / linux-image-4.4.0-040400-generic
4.4.0-040400.201601101930. The kernel lockups did *not* reproduce.
Two caveats:
(1) I did get this kernel warning in the log:

but it seems to be a completely different thing from the lockup back
traces seen with the 3.13 kernel.
(2) rr complains:
1134: [FATAL /home/petmay01/src/rr/src/Monkeypatcher.cc:660:patch_after_exec_arch<rr::X86Arch>() errno: 0 'Success']
1134: -> Failed to monkeypatch vdso: your __kernel_vsyscall() wasn't recognized.
1134: Syscall buffering is now effectively disabled. If you're OK with
1134: running rr without syscallbuf, then run the recorder passing the
1134: --no-syscall-buffer arg.
1134: If you're *not* OK with that, file an issue.
which indicates that it's not happy with running under a 4.4 kernel in
some way, and the code being run won't be the same as it was under the
3.13 kernel. (I filed https://github.com/mozilla/rr/issues/1627 against
rr about that.)

Title:
running 'rr' make check causes kernel "hard LOCKUP"
Status in linux package in Ubuntu:
Confirmed
Bug description:
Running the 'rr' make check on Ubuntu Trusty causes the machine to
become unusable because the kernel crashes. (rr build-and-make-check
instructions: https://github.com/mozilla/rr/wiki/Building-And-
Installing)
This is 3.13.0-74-generic #118-Ubuntu for x86_64.
This is rr bug https://github.com/mozilla/rr/issues/1614 (which
includes information about a Debian Jessie kernel crash initially and
also the Ubuntu crash later on in the same report), but since crashing
the kernel is a kernel bug I'm reporting that part here.
