Description Nate Clark 2017-01-25 18:56:18 UTC

Description of problem:

device md1 was being stopped and around the same time udevd tried to scan the /devices/virtual/block/md1 which caused an Oops.

Version-Release number of selected component (if applicable):
kernel-4.9.4-201

How reproducible:
Not very since it seems to be a tight timing issue.


Steps to Reproduce:
1. mdadm --stop <md>

Actual results:
Oops occurs and systemd-udevd is killed

Expected results:
Kernel returns appropriate error for the device not existing anymore to udevd.

Comment 1 Nate Clark 2017-02-06 18:12:44 UTC

Here are three more panics that seem to be related to accessing sysfs using the pr-allocated buffer path. These did occur on two different systems but the same hardware model.
