Broadcom bmcdhd crashing when re-associating wifi AP

zlacelle · May 21, 2018, 9:30pm

I see this happening with two separate TX2 boards, each at JetPack 3.2. The BroadCom bcmdhd kernel module seems to crash when the connection is forced to re-associate.

The initial connection will work fine, using NetworkManager. Then, after some time–anywhere from 10s to 5 min–the connection will attempt to re-connect and will fail.

This was happening with the standard 28.2 kernel (4.4.38) as well as the rebuild kernel I’m using for FireWire.

Full log is at the bottom of the post. Notably, here’s the crash:

I’m not sure how to approach fixing this. I can try a new version of the broadcom driver, but I’m not exactly sure which driver the Tegra is using or where to get the most up-to-date source.

zlacelle,

Could you describe the setting of your environment? According to your statement, this happens to 2 tx2 operating at 5GHz. I would like to know if this happens to specific AP or every AP. Please try to narrow down the cause if possible. Thanks!

zlacelle · May 22, 2018, 12:26pm

Sure! There are 2 TX2s running L4T 28.2, each separately having the same issue. This is happening with the only AP set I have available: a Cisco managed wifi solution. I will try to get a simple AP set up and see if it happens there.

Here’s the iwlist, with unnecessary IE removed:
