I am getting my dmesg spammed by what appears to be a usb (?) module, I can’t trace it back to anything, and this thing makes reading dmesg and syslog impossible:
android_work: did not send uevent
Any idea what it is and how to disable it?
I’m using the latest Jetpack on a TX2.
Which jetpack release you are using?
Please attach full dmesg
Any usb device you connect on the board?
Did same error happen to other TX2?
Hi Wayne,
I’m using 4.6, part of the dmesg is attached below (it spams too fast for me to copy paste much of it).
However I think I figured it out, I had the micro usb connected from when I flashed the TX2. The USB was connected to my PC, and I suspect the TX2 was trying to mount it as an android device for some bizzare reason. I haven’t seen it happen before to a TX2, TK1 or Jetson Nano.

What’s the module/library that this corresponds to?
No usbs connected,
It is happening on multiple TX2s
R32 (release), REVISION: 4.4, GCID: 23942405, BOARD: t186ref, EABI: aarch64
