Hi, I've seen this only once, and can't reproduce it. But here it is anyway: https://postimg.org/image/pn94k1yov (Not sure png files are accepted on LKML.) This occurred in a VM while booting 4.11.0-rc1 Cheers, -- Luís

A little context usually helps quite a bit when tracking things like this down. Eric

As I said, I just booted a VM with this kernel and when I looked again I saw this. I assumed this happen during boot. I had used this kernel in this VM before without problems, and I still use it -- only saw this once. I'll keep an eye on it and see if I can gather more info if it happens again. Cheers, -- Luís

Unfortunately, it's difficult to tell what went wrong with just the posted backtrace. If you built the kernel with debuginfo, the output of addr2line could help quite a bit. Thanks. -- tejun
