https://bugzilla.suse.com/show_bug.cgi?id=1225217 Bug ID: 1225217 Summary: OpenSUSE TW won’t boot without the “dis_ucode_ldr” parameter Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: charafweb@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- My specs: CPU i7 6700HQ, Nvidia Geforce 960M, 4k Screen, 16GB RAM, 512GB SSD, and 2TB HDD (ASUS Laptop N552V). OpenSUSE TW won’t boot without the “dis_ucode_ldr” kernel boot parameter. I removed the “quiet” boot kernel parameter to get error output, but unfortunately, nothing shows up; the boot process stops very early. Even on a fresh install with default open-source drivers, I’m facing the same issue. So, it doesn’t seem to be related to the Nvidia drivers. In fact, openSUSE boots without any issues the first time because the Intel microcode isn’t installed. But once it’s installed, the boot process hangs. I’ve tried several rolling distros that use version 6 kernels, they all present the same problem. Only kernel 6.1.x seems to work with Intel-ucode (tested in Manjaro). OpenSUSE Leap (kernel v. 5.x) works fine even when installing ucode. So, I thought the issue might be with the ucode for TW. I tried copying the microcode file (06-5e-03) from Leap and replacing the one in TW, following successfully all the necessary steps to install it manually, but the boot process continues to hang with no output. Microcode code for i7 6700HQ is not updated anymore, the latest version is microcode-20220510. It’s possible that something broke with kernel versions above 6.1. -- You are receiving this mail because: You are the assignee for the bug.
