BTW.. here is the crash.. is just a matter of generating a little load on apache2-event and something goes crazy.Is there a fix known? The traces below look pretty hopeless. Are they the first info printed? What's before them?Do You have any hints how to proceed here ? I have both compiled custom kernels and used SUSE packages plus kernel.softlockup_panic = 1 kernel.unknown_nmi_panic = 1 kernel.panic_on_unrecovered_nmi = 1 vm.panic_on_oom = 1 and kdump in order to get a workable backtrace, with no avail, machine hangs and the kernel dump is never written.With a debug kernel I get this at shutdown, but I am not sure it is related at all.
