--- Comment #9 from Nick Lewycky <nicholas at mxc.ca> ---
I'm afraid the workaround has no effect on the corruption. Tried both on distro
kernel and at drm-tip.

I also looked for other 'pm_qos_latency_tolerance_us' and found them under 
00:15.0, 00:15.1 and 00:15.3 (all of them I2C, not related to nvme). They were
set to 'auto', setting them to '0' had no effect on the corruption.
