Boot failed and there is no print on the screen!
If both set Memory model (sparse Memory) and Sparse Memory virtual memmap,

Hi all,
CONFIG_KMEMCHECK=y and set command-line kmemcheck=1, I find OS
boot failed. The kernel is v3.14.0-rc3
If set kmemcheck=1 nowatchdog, OS will boot successfully.
Here is the boot failed log:

I have automated kernel boots
However, my strong suspect is the following:

mm: fix process accidentally killed by mce because of huge page migration
I don't see how this could cause problems, none the less, I will test without
these changes and let you know.

Hi Vegard,
In some scenes, user want to check memory dynamicly, this dynamically
means we can turn on/off the feature at boottime, not runtime. Without
this patch, if user want to use this feature, he should change config
and build the kernel
;
+ if (second_pass) {
+ /* Skip devices offlined by the first pass. */
+ if (pn-put_online)
should it be if (!pn-put_online) ?
Thanks

I write a module, and find kdump can't boot in this case.
kernel version is 3.12, Intel(R) Xeon(R) CPUE5620

I write a module, and find kdump can't boot in the following case.
Kernel version is 3.4.24, Intel(R) Xeon(R) CPU E5620, and kernel v3.12
has the same problem too.
Here is the code:
struct timer_list g_timer;
void tmrhnd_invtssfault(unsigned long data)
{
long __res;
Use __free_reserved_page() to simplify the code in the others.

Function is_memblock_offlined() return 1 means memory block is offlined,
but is_memblock_offlined_cb() return 1 means memory block is not offlined,
this will confuse somebody, so rename the function.
Another, use pfn_to_nid(pfn) instead of page_to_nid(pfn_to_page(pfn)).

OS boot with kmemcheck=0, then set 1, do something, set 0, do something, set
1...
then I got the WARNING log. Does kmemcheck support dynamicly adjust?
