Raspberry PI + Stickminer: dmesg warning issue WARN::dwc_otg_hcd_urb_dequeue

Maybe this can help someone else running a Raspberry PI with stick miners, like CompacF and others. I’m on the standard 64-bit Raspberry PI OS (Bullseye). If you’re getting a ton of warnings in dmesg like this: It eventually messes up USB performance, and it’s all because the 64-bit driver doesn’t fully handle FIQ (whatever that is!). Check out this thread: here. To fix it, just add this to the end of your /boot/cmdline.txt command line settings. This will turn off FIQ, and after you reboot, you won't see those error messages anymore, plus your USB performance should be back to normal. I hope this helps you too. It definitely sorted out the issues I was having. Cheers, G. P.S. This tweak seems to have taken care of those annoying PT_NONONCE resets I was dealing with on the CompacF's while using CGMiner. My rig's stability has greatly improved since I made this change, and my average hash rate has gone up a bit too. So if you’re using a Raspberry PI with the 64-bit Stock OS, check dmesg to see if you’re facing the same problem.

Which Pi? 1, 2, or 3, 3B, 3B+? Orange Pi?

Only Raspberry PI series and only when using the stock Raspberry PI 64bit OS, it doesn't seem to happen on the 32bit version of the OS. I've tested on Raspberry PI 3B, 3B+, 4B and Zero 2W. Each show the error when using the 64bit OS. Orange PI is not related to Raspberry. Completely different vendor, hardware and OS build. I've not tested an Orange PI as I dont have one. I did try a Pine ROCK64, that worked without any issues.
