I just put a 'if (!l3) return 0;' into cache_grow, the backtrace is the one from the initial report. Reverting 04231b3002ac53f8a64a7bd142fde3fa4b6808c6 does not change anything. Since -mm boots further, what patch should I try? The kernel boots on a different p570. See attached dmesg. huckleberry boots, cranberry crashes.
