@kernelkernel I see you're using USB OTG. The most known source for this bug is tring to sleep in a completion handler. So, if you try to sleep in a bottom_half (e.g., tasklet) you'll also see this error. Look at your ISR to see if you're using a schedule_tasklet call. If so, look in the tasklet to make sure it's not trying to sleep (wait_event, etc.) Also, look at your kernel timers for similar logic.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
