incidentally (or maybe not so incidentally) that got fixed yesterday in 
-tip - at around the time i triggered that crash:

  350f8f5: x86: Eliminate redundant/contradicting cache line size config options

See the full commit below. The config that triggered the crash for me 
has:

  CONFIG_X86_L1_CACHE_SHIFT=4

so it's 16 bytes - and it's consistent now, which is a new angle. So i 
think this explains why it stayed dormant for such a long time - it was 
hidden by the cacheline-size config value inconsistencies.
