I open a bugreport for this? Does this happen for others as well?

Did it happen with 11.2-GM kernel? If it's a regression from the
older 2.6.31, it'd be easier to find the cause.

If so, the commit below smells, judging from the stacktrace...

Yeah you are probably right. Jeff I think it is a bit dodgy to call
random core code like this from the swapper thread... If we haven't
called at least do_basic_setup then we haven't got things like
workqueues or got all our initcalls called.

do_basic_setup is after smp_init, which is what you need to run the
early acpi setup before. So we have a bit of a problem.
