Subject: hang on early boot, numa init code stack overflow?
Date: Wed, 22 Jan 2014 11:32:44 -0500 [thread overview]
Message-ID: <20140122163244.GA24936@redhat.com> (raw)
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
