[RESOLVED] Win2012: STOP 0x9F_4_IMAGE_CsvFs.sys

  • Article

Status: Resolved.

130624: Turns out this issue was caused by a storage problem.

130211: This issue is triggered when a machine is handling a surprise removal for a Csv volume. Nothing conclusive yet, but I wanted to see if there is anyone out there with the same issue. The 0x9F code indicates that a driver has failed to complete a power IRP within a specific time (usually 10 minutes).

The failure bucket is:

0x9F_4_IMAGE_CsvFs.sys

When you have a dump with this bucket, start with running !pnptriage. The stack of the relevant device event thread will show:
