Thank you for the response! I ran memtest from the GRUB boot menu and let it run for 3 passes - it reported no errors.
Next I booted into an Ubuntu 24.04 live ISO and to my surprise the desktop environment hung after login, just the same as on my live system! I flashed an Ubuntu 22.04 live ISO and had the same result when booting into it. This is perhaps unsurprising as it looks like the newer 22.04 ISOs are using kernel 6.8.0-40, as I saw when inspecting the bundled vmlinuz image in the one I flashed. I could, however, edit the GRUB command-line on live ISO boot and switch to single-user mode, which was functional. From there, I ran "short" self-test via smartctl for 1 minute and it reported no errors. Here are the statistics shown: Spin_Up_Time 0 Start_Stop_Count 0 Reallocated_Sector_Ct 11 Power_On_Hours 15314 Power_Cycle_Count 907 Unsafe_Shutdown_Count 87 Host_Writes_32MiB 82277 Workld_Media_Wear_Indic 11812 Workld_Host_Reads_Perc 0 Workload_Minutes 3658413212 Available_Reservd_Space 0 Media_Wearout_Indicator 0 End-to-End_Error 0 I also ran fsck on my root ext4 partition on the HDD and it reported that it was clean. I did see in the smartctl output that a firmware update from Intel was recommended, so I flashed and ran the firmware update tool provided at https://downloadcenter.intel.com/download/26491. This reported that there were no Intel devices attached though, so I guess that might have been a false positive. How would you recommend proceeding? Did I miss some diagnostics on memtest or smartctl, or do these results indicate that the hardware is more or less functional? The fact that the system hangs on the new kernel version even from the live ISO, but does not have any issues with the old kernel version (even with all other system files the same), seems to indicate to me that it really is a conflict with the new kernel, and not a hardware issue or problem with corrupted files. But, I could be wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080182 Title: System hangs after GDM login with 6.8.0 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2080182/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
