Reverting that commit is not the best idea. Let's start with the usual:
- Kernel version
- dmesg on both sides (host and device)
- dwc3 tracepoints:
# mkdir -p /t
# mount -t tracefs none /t
# echo 8192 > /t/buffer_size_kb
# echo 1 > /t/events/dwc3/enable
# echo 0 > /t/events/dwc3/dwc3_readl/enable
# echo 0 > /t/events/dwc3/dwc3_writel/enable
This should be enough to tell me what's really going on.
