Nothing?

I think you must explain in details what happened, what did you/program do when it occurred? Can you reproduce it? how? have you done any configuration? which OS? Raspbian?

I try to answer all this questions:

I can´t reproduce it. It occurs sporadically once or twice a day.
I think it started when I update the kernel.

I'm using raspbian lite.

Which raspberry is this on and which storage card do you use?

It only happened ONCE - and I´m not sure (and can´t reverse check with "/var/log/apt/history.log" (cause it´s empty)) if it is/was related to package updates; I think there recently were ones kernel related, weren´t they?

What's the connection? The symptom - a hung task - can have many different causes.

net/mlx5: Fix a WARN upon a callback command failure
5d3f7d3 
[ Upstream commit cc80915 ]

The below WARN [1] is reported once a callback command failed.

As a callback runs under an interrupt context, needs to use the IRQ
save/restore variant.

net/mlx5: Fix a WARN upon a callback command failure
fc18f59 
[ Upstream commit cc80915 ]

The below WARN [1] is reported once a callback command failed.

As a callback runs under an interrupt context, needs to use the IRQ
save/restore variant.
