I'm using a linux-socfpga altera (intel) patched kernel, and they don't have a 5.19 kernel available. In any case, nothing outside of the dwc2 driver could possibly fix this problem. Arguably, it is a bug (or at least major deficiency) in the synopsis hardware, in that it does not support reliably scheduling the complete splits. Or you could view it as a deficiency in the usb standard, in that it does not consider error handling in the case where complete splits are late.
