I have an ASUS ProArt Z690 Creator WiFi running an Intel i7 12700K, latest bios offered by Intel. I've got 64GB of RAM in this workstation. If I try to boot Fedora 40 or Fedora 41 (Any spin) I get to the GRUB menu, select "install" and then it immediately goes to "Out of memory. Press any key to continue." With no additional details provided. This does NOT happen with AlmaLinux 9, but does happen with other similar distros such as recent Ubuntu releases. So it appears that something broke with Grub between the branching of RHEL9 and Fedora 40. I'm more than happy to test / debug, but unfortunately grub itself provides very little troubleshooting information. See "Additional Info" for troubleshooting steps I've tempted so far. Reproducible: Always Steps to Reproduce: 1. Boot Fedora 40 or 41 2. Select Install 3. Immediately errors out with a grub out of memory error Actual Results: Goes "out of memory" with no additional information such as how much memory it detected or tried to get but failed. Expected Results: Successfully launches live environment This same issue comes up with Fedora 40 and 41, but weirdly not AlmaLinux 9. I've already tried to debug this via... * Unplugging monitors * Turning off IOMMU in the UEFI * Turning off Thunderbolt support in UEFI * Updating UEFI to latest
Hi Eric, could you please try installing again..? When you get to the grub menu, hit `e` then add the line `debug=linux,regions` and press Ctrl+x to execute the entry. You should get some debug info from grub, and if you could capture it and paste that here, it should help. Also, a memory map could be helpful: from the grub menu, hit `c` to get to the grub prompt and then type: `lsefimmap` and then try to capture the output. (if you `exit` from there, you'll get back to the menu) thank you.

Hi Marta, unfortunately the two times I attempted debug=linux,regions both resulted in a hung system after hitting "ctrl+x"-- it no longer goes out of memory, but my system is hardlocked. lsefimmap was more successful, but it was a lot of output on a very tight display (im guessing it defaulted to 800x600 or similar) so I had to pager it and upload it in chunks. See attachments.
Hi Eric, thanks so much for the memory map from grub. And thank you for trying to get the debug info. I can't understand why it would cause your system to hang like that.
This message is a reminder that Fedora Linux 41 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '41'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 41 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
Eric, can you check comment 86 from https://bugzilla.redhat.com/show_bug.cgi?id=2263643#c86 ? OOM issues (as this one) are marked as duplicated of https://bugzilla.redhat.com/show_bug.cgi?id=2263643 so further queries should be done on latter one please.
