ffff8800010a7000 should be OK, as crashkernel=64M@16M was passed to the

This is strange. As you said, ffff8800010a7000, should be a valid address
as you reserved memory from 16M.
I took above -mm and for me kernel loads fine. I reserved memory 64M@32M
as by default kernel is loading at address 16M.
How does your /proc/iomem look like in first kernel?
Thanks

Hmm, PMD has not RW bit set and we do store (see below).

I'm not any longer on that machine. init_pgtable() overwrites random
memory, so possibly even host's page tables, hence the oops above, I
suppose.
I'm currently chasing it down in the qemu virtual machine, since I
already got a garbage into my ~/.viminfo (some overwritten page got
flushed, I guess).
There /proc/iomem looks like:
00100000-12beffff : System RAM
01000000-04ffffff : Crash kernel
01000000-014680c2 : Kernel code
014680c3-016f39f7 : Kernel data
0175b000-017d97ab : Kernel bss
I'll keep you informed.

Hmm.., this looks fishy. Reserved memory is starting at 16MB at the same
time first kernel is loaded at 16MB. So when we try to load a crash kernel
it can try to overwrite existing kernel.
In the past if crash kernel memory area used to overlap with kernel code,
data or bss, we would not reserve the memory for "Crash Kernel" and this
entry would not appear in /proc/iomem. Not sure what has changed.
Anyway, can you just try reserving memory at some other address, say
64M@32M and see if it works.
Thanks

Yup, that's it of course. I missed it overlaps with current kernel. I
though they are areas for the crash kernels. Thanks for pointing out. So
the error is we reserve the space for kdump even we can't in fact?

Please cc me on mmotm bug reports!
There's a -mm-only debug patch:

I forget why it was added.
It looks like it's blaming the open-coded notify_change() call in
devtmpfs_create_node().

FTR, it moved to git://zen-kernel.org/kernel/mmotm.git and the

How did you find out? Don't get wrong by the topmost commit and tag dates...
It definitely looks weird, but is the latest :):

I asked the same question to mmotm git tree maintainer last month.
Currently mmotm git was gone by unhappy thing. and akpm stoped his recovery.
because akpm plan to get -mm into linux-next. He said please wait few weeks.
I guess akpm is pretty busy now. (guessing because recent mmotm commit mail
was not so active). then, I'd like to answer you instead. I hope this mail help you.
Thanks.
