Subject: WARNING: at mm/page_alloc.c:4514 free_area_init_node+0x4f/0x37b()
Hi,
I'm hitting the WARN_ON in $Subject with latest linus:
v3.5-8833-g2d534926205d on a 4-node AMD system. As it looks from
dmesg, it is happening on node 0, 1 and 2 but not on 3. Probably the
pgdat->nr_zones thing but I'll have to add more dbg code to be sure.
Config is attached.
dmesg:
