Hi Hauke,
I would guess something to do with the conversion of the CPU interrupt
controller to IPI domains by patchset
https://patchwork.linux-mips.org/project/linux-mips/list/?series=255&state=*,
new in 4.12, has broken your IPIs and a CPU is getting stuck waiting for
the other to respond.
Note that Paul says the Lantiq part of patch
https://patchwork.linux-mips.org/patch/15837/
(1eed40043579608e16509c43eeeb3a53a8a42378) has only been compile tested.
Thanks,
Matt

Hi,
I just tried to boot Linux 4.12-rc1 on a Lantiq Xway xrx200 board and
boot failed when I had CONFIG_MIPS_MT_SMP enabled.
It works with SMP on 4.9 and I think I also tried 4.11-rcX, but I am not
100% sure. I will investigate this problem further on Friday.
If someone has an idea what I should test, I will do it on Friday.
Both boot logs are attached to this mail.
