That patch fixes a different problem. The assertion shouldn't have been made for hugetlbfs regions. I can only assume we are not triggering the same problem. According to your .config, DEBUG_VM is not even set so this is some other problem. Do you know what line triggered the problem? Eric Munson is currently investigating this as I'm chasing down another bug but my understanding is that right now he can't reproduce the problem. How reproducible is this for you?
I cannot recreate this consistently. Sometimes i am able to recreate , but it's random. I have seen this problem on 2 out of 4 power boxes. Here are last few lines from the hugetlbfs test run. get_huge_pages (32): PASS get_huge_pages (64): PASS quota (32): PASS quota (64): PASS counters (32): PASS counters (64): PASS mmap-gettest 10 20 (32): PASS mmap-gettest 10 20 (64): PASS mmap-cow 19 20 (32): PASS mmap-cow 19 20 (64): PASS set shmmax limit to 335544320 shm-fork 10 10 (32): PASS shm-fork 10 10 (64): PASS shm-fork 10 20 (32): shm-fork was executed when the oops occurred.
