I think I have a reproduction here - if I check that the number of bytes transferred in an isochronous packet is an integer multiple of sample size, I occasionally...

Ah, 64-bit kernels are incompatible with ARM's FIQ handlers, so the FIQ code is demoted to a regular IRQ handler. The only workaround is to specify arm_64bit=0 in /boot/config.txt and...

The linked commit adds arm64 architectural support for FIQ handlers but there's quite a bit of plumbing required to get dwc_otg to use it. It's low priority, so won't get...

Not really. Question: what happens if you have two identical touchscreens plugged into a hub thus sharing a root port? Does the bus string expand into a route string (e.g....

Without hardware that fails in this exact way, we will be unable to reproduce your issue.

You need to have TinyUSB in your include path.

This appears to be resolved as of 2.0 rc7 (not using the exact failing flash storage as last time, but a device that's similarly slow to write)

I2S (via convoluted setup in sound/soc/soc-generic-dmaengine-pcm.c) sets only the peripheral's buswidth. I assume that because tx/rx is effectively continuous, the trapped residue for rx doesn't matter?
