After two more weeks, I can now confirm that cherry-picking fb1522e099f0
onto earlier 4.13-rc kernels makes things _WORSE_.
I believe that
- plain 4.13-rc4 works fine and allows stable usage of KVM
virtualization
- 4.13-rc4 with cherry-picked fb1522e099f0 is bad, causing random
segfaults and file-system corruption in VMs under disk and CPU load
- 4.13-rc5 is bad either way
I will start bisecting between 4.13-rc4 and 4.13-rc5, hoping that this
will yield better results. Since I have to wait between three to five
days to flag a kernel as "good" without too much doubt, and bisect
4.13-rc4..4.13-rc5 will take "roughly 7 steps".
I am open to additional suggestions.
Greetings
Marc
