the patches look ok, but i found another problem that predates this one:
http://pastebin.ubuntu.com/8177366/
the oops starts in the bridge code but is related to the JUMP_LABEL feature:
arch/Kconfig:
config JUMP_LABEL
bool "Optimize very unlikely/likely branches"
depends on HAVE_ARCH_JUMP_LABEL
help
This option enables a transparent branch optimization that
makes certain almost-always-true or almost-always-false branch
conditions even cheaper to execute within the kernel.
...
and i'm wondering if it has anything to do with the hw that i'm testing
right now: cortex-a15, calxeda ecx-2000 midway in this specific case
I'm looking into it.
