Hi

 

the following messages are spamming my Unraid log every couple of seconds:

The messages refer to my USB4/Thunderbolt controller:

I have a Thunderbolt monitor connected there and it's working perfectly fine. So I really do not understand these messages. I can only imagine that these are coming from the 2nd USB4 port, but there is nothing connected there.

 

This Thunderbolt controller is part of a combo chip ASM4242 which consists of a USB4 and Thunderbolt controller. In my setup the Thunderbolt controller (group 32) is controlled by the host whereas the USB4 controller (group 31) is passed through to the VM. This is needed for the upstream USB of the monitor's integrated KVM to work ant get keyboard and mouse routed into the VM.

 

Unfortunately AsRock did not implement any USB4/Thunderbolt options in my motherboard's BIOS. There support told my, all options are enabled by default. This means I cannot enable/disable any potential "power settings".

 

How can I debug or fix that or at the very least configure an "ignore rule" so that my log is not useless?

 

Thank you very much!

If you are on 7.0.x or early, try updating to 7.1.0-rc1 and retest, the newer kernel has improved Thunderbolt support.

I'm on Unraid 7.0.1 but already using Kernel 6.14.rc5. I need this for my AMD RX9070. I tried to upgrade to 6.14 but this "breaks" Unraid when shutting down the VM with the RX9070 passthrough.

 

Is there a filter for the log? I'm happy to just blacklist this message. As I said everything seems to work just fine.

Not that I know of.
