1. Please describe the problem: 1.1-Migration from Fedora 29 (latest release) to Fedora 31 (5.3.12-300.fc31.x86_64) worked fine: I recovered the same environment; successful several boots and reboots. In the dual boot menu both Fedora 29 and 31 kernels appear, as well as a rescue kernel and the Windows boot manager. 1.2-Update to Fedora 31 (5.3.13-300.fc31.x86_64), from the upgrade graphical menu. 1.3-UNABLE to re-boot: black screen and unable to access the Linux directories (/home ….). The Windows boot still works, but none of the three fedora releases works (Fedora 31_5.3.13, Fedora 31_5.3.12, Fedora 29, Fedora rescue). 1.4-Successful installation of Fedora 31 (5.3.7-301.fc31.x86_64) on a new raw partition of the disk from Live USB (created with Fedora Media Writer). Boot and reboot worked fine. 1.5-UNABLE to reboot after the upgrade to Fedora 31 (5.3.16-300.fc31.x86_64) within the upgrade menu: stuck on black screen. 1.6-SAME results after reinstallation from the USB key, upgrade to 5.3.16-300 and manually update with the commands sudo dnf update –refresh and then sudo grubby –update-kernel=ALL –args=”dis_ucode_ldr” or typing directly ”dis_ucode_ldr” in the command line of the boot menu on the screen. 1.7-Removing the argument “quiet” in the command line of the boot menu does not result to any info on the screen: this tends to point to a bug right at the beginning of the launch procedure. 1.8-I have updated the BIOS and the Intel chip drivers via the Dell Assist software. 1.9-Since the problems does not occur just after the migration form Fedora 29 to 31 and just after the installation from USB, I am inclined to think that it has to do with the upgrade procedure that is built in the Fedora 31 distribution (although I am not expert in that matter). 1.10-So my questions are: i) what is the stable solution to this problem (I cannot rely on a system which stops after the first update) and ii) is there a way to recover the existing Linux partition that are still on the PC (without starting from scratch, and loosing the existing environment). 1.11-Thanks in advance for any help. 2. What is the Version-Release number of the kernel: 5.3.12-300.fc31.x86_64 5.3.16-300.fc31.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : See above 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Yes, see above 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Black screen, I have no access to the OS 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Black screen: I have no access to any file, journal, etc...!!!
Thank you for your bug report, this appears to be a duplicate of bug 1779611, so I'm marking this as such. It seems that this is an issue with various Inspiron models and unfortunately we do not know the root cause yet. *** This bug has been marked as a duplicate of bug 1779611 ***
