Hi Wesley, All, I see a reboot loop on Xiaomi Pocophone F1 (sdm845) with TX FIFO resize patches which landed in v5.15-rc1. Upstream commit cefdd52fa045 "usb: dwc3: dwc3-qcom: Enable tx-fifo-resize property by default" to be specific, which switched on this feature by default. At times the phone crashes into the fastboot mode after the reboot loop, but mostly end up booting to UI after a while. This is what it looks like https://people.linaro.org/~amit.pundir/beryllium-userdebug/PXL_20210920_162749483.mp4. PocoF1 does support TX fifo resizing as I can see that in the downstream dts. So maybe it is the tx-fifo-max-num which need to be adjusted for the device? I couldn't find the tx-fifo-max-num equivalent in the downstream tree though https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/dipper-q-oss/ Curious if you had any ideas what might be going wrong? For now I'll keep digging around tx-fifo-max-num, but I figured I'd ask just in case it's obvious to you. Regards, Amit Pundir
