Network Freeze With Broadcom DKMS Wireless Driver

I can reproduce this bug locally by suspending my machine. This appears to always reproduce on 5.19.0-23-generic.

The patch in Debian doesn't apply cleanly, so I refreshed the patch for Ubuntu. Building and testing locally with the refreshed version appears to work (my reproducer doesn't reproduce with this package).

Steps:

1) Add new patch line in dkms config: debian/dkms.conf.in
2) add patch to debian/patches
3) build (dpkg-buildpackage -us -uc)
4) install and test

The attachment "0041-dev-addr-access.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Can we get the description updated with a test case and some regression potential? Thank you.

Hello Brett, or anyone else affected,

Hi Łukasz,

The test passes locally for me.

My reproducer, which works consistently on this machine, did not reproduce this issue using the new package. Suspending the machine was sufficient to force the error condition, but now that does not happen.
