To find out what has been crashed I enabled EFI pstore. Unfortunately there were no crashes after that. However, there are kernel BUG traces in dmesg. After several experiments I found strong correlation between ucsi_acpi driver and the crash. I blacklisted: blacklist typec_ucsi blacklist ucsi_acpi blacklist roles blacklist typec Two dmesgs are in attachment.
