dmesg with sysrq-w

my SUSE Thinkpad T495s
was previously working fine with kernel-default-5.3.18-lp152.44.1.x86_64

got stuck in all network operations after Wifi disassociated at 6567s uptime
(e.g. ip a, ping, wg-quick down)

lspci -nn has:
01:00.0 Network controller [0280]: Intel Corporation Wireless-AC 9260
[8086:2526] (rev 29)
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0e)

and
hwinfo --network also shows the docking-station ethernet:
  SysFS ID: /class/net/eth1
  SysFS Device Link:
/devices/pci0000:00/0000:00:08.1/0000:05:00.3/usb3/3-1/3-1.1/3-1.1:1.0
  Hardware Class: network interface
  Model: "Ethernet network interface"
  Driver: "r8152"
  Driver Modules: "r8152"
  Device File: eth1


eth* is not used. But maybe NetworkManager tried to activate eth1, because
there is a cable plugged in.
