Subject: kmemcheck: Fatal error; system fails to boot when kmemcheck enabled
Hi,
Kernel 3.4.4 with kmemcheck enabled does not correctly boot on my
system, which is a x86-64, Core i7 Sandy Bridge computer with Asus
P8P67-EVO motherboard. The errors seem to be related to ACPI, but
there may be other things wrong. Userspace programs, particularly init
and in other cases some other binaries run from initramfs die with
SIGTRAP.
I have been able to boot far enough to get usable backtraces with at
least the following four sets of options (after some research, I think
the "noacpi" and "noioapic" parameters are no-ops; mentioning them for
completeness). The "Modules linked in:" lines say only <omitted>,
because the lines become too long and cause netconsole to eat most of
the messages. Here is the list from the running system without
kmemcheck (first words of /proc/kmemcheck):

Got this. Note that the pci_find_upstream_pcie_bridge warning also
happens on a healthy system without KMEMCHECK:
