dmesg after reboot from Windows 10

I am on Lenovo Thinkpad T495. Since kernel version 5.4.1 I am getting strange issues related to MMC/SDHCI after direct reboot from Microsoft Windows 10, which are manifested by slow system response, a few kernel workers using 100% of CPU, and plenty of SDHCI register dumps in dmesg. If the laptop is powered off first, and then booted to Linux, no problems occur.

I am attaching dmesg after reboot from Windows and after clean boot. Also top of the hungry processes is attached.
