Subject: Re: Hung task in 4.9 using kvm 5.2

I'm unable to reproduce "BUG: unable to handle kernel paging request"
when I use 4.9.178-rt131, so I'm inclined to think that it got
introduced somewhere along the way to 4.9.271-rt182.
The problem with "hung task" is also gone when I don't force qemu 5.2 to
use cache.direct=true and aio=native. Qemu 2.1 from Debian Jessie does
not trigger this problem on the same system.
