Comment 51 for bug 76489

Looking back through the comments Giraya's observation that the PCI device flags change after rmmod/insmod is potentially a clue.

Could those affected collect reports from a fresh boot before the issue strikes. I'd like to see the result of lspci for the realtek device before and after rmmod/insmod. Collect all the information about the device using the attached script.

Download and save the script to a file (report.sh) and make it executable:

chmod a+x report.sh

Run it to gather a "good" report and then attach the resulting log archive to this bug report:

sudo ./report.sh good

When the issue next strikes run the script again, using "bug":

sudo ./report.sh bug

Attach /tmp/reports-bug.tar.gz to the bug report.
