I just noticed you said "Cannot access the system remotely as well.", which suggests a kernel problem.
Looking at your original kernel log you have: [ 15.680794] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_enable_smc_cac failed [ 15.712514] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_enable_smc_cac failed ... [ 22.768100] radeon_dp_aux_transfer_native: 242 callbacks suppressed ... [ 33.988147] radeon_dp_aux_transfer_native: 326 callbacks suppressed and in your most recent system log you have this error repeating again: Dec 03 09:44:34 avi kernel: [drm:si_dpm_set_power_state [radeon]] *ERROR* si_enable_smc_cac failed Dec 03 09:44:34 avi kernel: [drm:si_dpm_set_power_state [radeon]] *ERROR* si_enable_smc_cac failed While those messages might be harmless, they may also hint at a fault in the kernel graphics driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793595 Title: [radeon] Shell freezes, mostly when running chrome or editing text files.
