Greetings,
it took a while to find some time for bisecting, but finally:
after upgrading from 6.3 to 6.4, my old HPPA/PA-RISC box started
throwing traces and became unusable, details below. I'm a little
surprised apparently nobody else got bitten by this.
This still happens with 6.5-rc4, bisecting led to:
700d2e9a36b93601270c1e15550acde2521386c5 is the first bad commit
commit 700d2e9a36b93601270c1e15550acde2521386c5

mm, page_alloc: reduce page alloc/free sanity checks
Does this make sense? Anything I could try out?
