There seem to be some IO regressions in this kernel release,
we updated it and pushed a version to pvetest which should include fixes 
or revert the respective commits. Can you please try
pve-kernel-4.15.17-1-pve_4.15.17-8 [1]

if possible. Users in our Forum reported that this version fixed their
issues.

Hmm, from 4.13 to 4.15? I'll look into that...
