Hi Mark, Thank you to point me in the right direction, I have solved my problem by changing BIOS security configuration.
I have the security chip settings: - Security Chip Selection = Intel PTT - Security Chip = Enabled I enabled Discrete TPM and now 5.2 kernel suspend and resume properly. I also found this logs with Intel PTT: tpm tpm0: Operation Timed out tpm tpm0: Operation Timed out tpm_crb: probe of MSFT0101:00 failed with error -62 The system does not have a network connection after suspend (can't ping), but then I press Fn+ESC it toggle Fn led on and off (in normal condition no led are on and Fn+ESC resume system). -- Cheers, Anton
