Hi Tore,
Yes, this is a known issue starting with VMware Tools 12.5.x, especially on Windows VMs using paravirtual or LSI Logic SCSI controllers. The "Storport Miniport Driver has timed out a request" warning typically appears when the new VMware Tools storage I/O filters trigger delays under certain conditions, even without snapshots or backup jobs running.
Roll back to VMware Tools 12.3.5 or 12.2.5 - many users report stability returning after downgrade.
If you prefer to stay on 12.5.2, disable vmscsi
timeout warnings in the guest registry as a temporary mitigation:
Monitor storage latency - in some environments this exposes subtle I/O contention issues that became more visible with 12.5.x.

Hi Folks.
After installing VMware Tools 12.5.2 some weeks ago, I experience an increased rate of these ": Windows Storport Miniport Driver has timed out a request" warnings.
They occur on VMs that do not have snapshots, and not at the same time when centralized backups have been run on that particular VM.
Different MS version as well.
Have anyone else experienced the same?
