kernel 5.5.1 : lost suddenly USB mouse + keyboard (<=5.4.17 was fine)

[Toralf Förster]

Hi,

at a (5 year old) T440s  under a hardened Gentoo Linux I run 2x in the past 24 hours into a freeze for mouse and keyboard for this (docked) system:

	Linux t44 5.5.1 #6 SMP Sun Feb 2 17:25:06 CET 2020 x86_64 Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz GenuineIntel GNU/Linux

The log says:

The 2 lines shows that the system is still running. But I could only poweroff it and poweron it to get it back.
