Hi,
Using netconsole, I was able to capture a hard lockup that seems to be
related to cgroups, on a Fedora kernel based on v4.14.4.
By my analysis, from the 16 CPUs below, 14 are on css_set_lock, one is
inside css_task_iter_advance, and the last one stuck trying to send an

What about the kernel .text overflowing into the modules space? The loader
checks for that, but can something like that happen after everything is
up

Hello,
The following two patches address an integration issue between KVM and
KGDB. The issue described in the patches can be triggered with vanilla
kernels that enable KGDB and KVM together on x86 (more specifically,
we bump into this with Fedora's 3.11 kernel from FC19).
On a kernel enabled
We have seen that when kvm-unit-tests runs with kgdb enabled, the
kernel halts on the debugger during the KVM x86 instruction emulation
that performs a test of a division by zero, and also during fwait.
This patch adds calls that temporarily disable the debugger trap.
