Is there any bug report with some more details? It is much more preferable to fix the issue rather than to revert the whole thing right away.

Black screen, and netconsole was silent. No serial port on this machine unfortunately.

Thanks.

Looking closer, I _think_ that the bug is in set_highmem_pages_init->is_highmem and zone_movable_is_highmem might force CMA pages in the zone movable to be initialized as highmem. And that sounds supicious to me. Joonsoo?

Not sure there's anything particularly useful in it though since I've now seen this on all the highmem systems I've booted. BTW I just noticed that the reported memory sizes look pretty crazy: Memory: 3926480K/3987424K available (5254K kernel code, 561K rwdata, 2156K rodata, 572K init, 9308K bss, 56848K reserved, 4096K cma-reserved, 3078532K highmem) vs. Memory: 7001976K/3987424K available (5254K kernel code, 561K rwdata, 2156K rodata, 572K init, 9308K bss, 4291097664K reserved, 4096K cma-reserved, 7005012K highmem) > > [...] > > [ 0.000000] cma: Reserved 4 MiB at 0x0000000037000000 > [...] > > [ 0.000000] BUG: Bad page state in process swapper pfn:377fe > > [ 0.000000] page:f53effc0 count:0 mapcount:-127 mapping:00000000 index:0x0 > > OK, so this looks the be the source of the problem. -128 would be a > buddy page but I do not see anything that would set the counter to -127 > and the real map count updates shouldn't really happen that early. > > Maybe CONFIG_DEBUG_VM and CONFIG_DEBUG_HIGHMEM will tell us more.

It has CONFIG_HAVE_MEMBLOCK_NODE_MAP so the movable_zone initialization depends on quite some crazy movable init code paths.

Reserved pages clearly underflowed which suggested we are initializating more than we should.

And that sounds supicious to me. Joonsoo? > For a point of reference, arm with this configuration doesn't hit this bug because highmem pages are freed via the memblock interface only instead of iterating through each zone. It looks like the x86 highmem code assumes only a single highmem zone and/or it's disjoint? Thanks, Laura

With DEBUG_VM the machine doesn't get far enough to print anything on the serial console. DEBUG_HIGHMEM didn't give me any new output.
