We have recently been experiencing some issues with one of our TX-2 developer kits. Seeing lots of messages like this in /var/log/kern.log:

Jan 11 19:08:25 x kernel: [ 1382.665868] CPU4: SError detected, daif=140, spsr=0x20000000, mpidr=80000102, esr=bf000000

Jan 11 19:08:25 x kernel: [ 1382.667805]   Address = 0x0 (Unknown Device)

We also see some messages like this

We have been seeing these issues for a few days using JetPack 3.1. Wanted to rule out some type of software issue, so we loaded JetPack 3.2 and we are seeing the same issues.

Anyone have these issues before? Looks like the kit is going bad…

Hi kgdad,

If only happened on one TX2 module, event adopt it on other board is the same, can’t repro on other TX2 module, then you could consider to RMA - [url]https://developer.nvidia.com/embedded/faq#rma-process[/url]

  1. Go to [url]http://nvidia.custhelp.com/app/home[/url]
  2. Select “Live Chat” option to chat online with one of our customer care agents.
  3. Enter your contact information.
  4. Select the “Jetson” from the product drop-down list.
  5. Submit the request.

Thanks

We haven’t seen this on any of our other boards so I think it might be bad hardware. Will follow the steps provided.

Thanks!
