Created attachment 1663908 [details] dmesg of any kernel outputs the same timeout 1. Please describe the problem: Built-in SD reader does not work dmesg is flooded with timeouts (no matter if a card is inserted) 2. What is the Version-Release number of the kernel: Probably any 5.x kernel, maybe even below 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at Sorry, can't remember if it worked years ago (but it's working in Windows) 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Every time. dmesg contains repeatedly: [ +0,000001] mmc1: sdhci: ============================================ [ +10,240071] mmc1: Timeout waiting for hardware cmd interrupt.

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``: Yes 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.
