Updated kernel to 4.19.15-041915-generic (ukuu), and still this reproduces.
Right after boot it works fine, then after one working day I disconnect thunderbolt and suspend the machine. Then next morning it reproduces within first hour. With the current setup I don't have any usb devices connected to the dock (TB18DC), only integrated devices (ethernet and audio) and DP ports are in use. Dmesg looks about the same as earlier.
