Kernel module ch341 in Ubuntu kernels 5.4.0-88-generic i 5.4.0-89-generic cannot program any esp8266 chips with ch340 chip uart controller. In kernel 5.4.0-86-generic everything is working good

Ubuntu 20.04.3 LTS
Kernel module ch341 in Ubuntu kernels 5.4.0-88-generic and 5.4.0-89-generic cannot program any esp8266 modules like Wemos D1 mini which contain ch340 chip uart controller. In kernel 5.4.0-86-generic everything is working good.
Communication over serial connection is working in both cases only programming using esptool is broken, kernel module do not react properly to response fom ch340 chip I suppose
