To find out what has been crashed I enabled E= FI 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.=20 The messages to search: ucsi_acpi USBC000:00: possible UCSI driver bug 2 ucsi_acpi USBC000:00: error -EINVAL: PPM init failed --=20 You may reply to this email to add a comment.
