| |
I'm seeing a hang during boot on my test box running the current tree, It doesn't always happen, perhaps one in five boots. I managed to get a partial trace after booting with earlyprintk=vga
dump_stack panic ? numa_clear_kernel_node_hotplug __stack_chk_fail numa_clear_kernel_node_hotplug ? memblock_search_pfn_nid ? __early_pfn_to_nid numa_init x86_numa_init initmem_init setup_arch start_kernel
Looks like something overflowed the stack. This is just a quad-core i5, nothing fancy numa-wise.
This code was added in a0acda917284183f9b71e2d08b0aa0aea722b321
