Hello

I reproduced the problem, this is probably due to:
[2.826112] reg-fixed-voltage usb0-vbus: error -EINVAL: can't get GPIO
[2.832674] reg-fixed-voltage: probe of usb0-vbus failed with error -22

bisecting in progress... stay tuned.

Regards

[linux-sunxi] [regression] fail to detect USB driver partition for OrangepiPC

2022-01-17 Thread zhang...@gmail.com

hi, All

I use same kernel config for both 5.15.14 and 5.16.0,

for 5.16.0, USB driver is detected, but failed to detect partition,
use strace fdisk -l /dev/sda , it blocked at open("/dev/sda")

occasionally it can detect partition, about 1/20 possibility.

thus I guess, it may related to boot order, but I don't know how to find it.

my kernel config: 
https://gitee.com/zhangn1985/config/raw/master/linux.arm.conf

BR.
Ning.
