Hello,

Our users tested the RC1 of kernel 4.19 on their P5020 boards today. Unfortu=
nately the USB bug still exists. With mem values bigger than 4096M, the USB m=
ouse and keyboard doesn=E2=80=99t work. With the bootarg mem=3D4096M, the US=
B devices work without any problems. Please compile the RC1 and test it on y=
our P5020 board. There is a problem with the memory management since 22/08/1=
8.=20

Thanks,
Christian

I don=E2=80=99t have a P5020 board here. That means I can=E2=80=99t bisec=

t and test. Therefore I need your help. The problematic Git commit must be s=

The Git kernel from 22/08/18 1:20 PM UTC works with USB devices.
Could you please compile a Git kernel and test it on your P5020 board?
