Kernel 6.18 Freeze on Intel 13th Gen Raptor Lake When Connecting USB-C Monitor

Hello Fedora community,

This is my first post asking for support troubleshooting an issue, so please go easy on me. I’m currently facing a problem that I initially brushed off as a kernel regression, but I have a gut feeling it might be a configuration issue on my part. On my Fedora 43 with kernel 6.18, I’m experiencing a hard freeze on my Intel 13th Gen Raptor Lake laptop whenever I connect a USB-C to DisplayPort 1.4 monitor.

Whenever I boot into kernel 6.18.x (any kernel from the 6.18 series, no update has resolved this issue so far, I just tested it with vmlinuz-6.18.7-200.fc43.x86_64 and the issue persists), log into the desktop environment (KDE Plasma, plasmashell 6.5.5), plug in the USB-C to DisplayPort cable connected to the AOC CU34G4 monitor set at 3440x1440@120Hz HDR the system freezes immediately. Unplugging the cable allows me to regain control.

journalctl logs show a failure in Alt Mode negotiation, with the device falling back to the “USB 2.0 BILLBOARD” class:

Jan 19 18:40:14 fedora kernel: usb 3-8: new full-speed USB device number 5 using xhci_hcd
Jan 19 18:40:14 fedora kernel: usb 3-8: not running at top speed; connect to a high speed hub
Jan 19 18:40:14 fedora kernel: usb 3-8: New USB device found, idVendor=2109, idProduct=0103, bcdDevice=a0.52
Jan 19 18:40:14 fedora kernel: usb 3-8: Product: USB 2.0 BILLBOARD

This setup works perfectly on kernel 6.17.12 (running 3440x1440@120Hz HDR). I have attempted to isolate the issue by blacklisting the xe driver and disabling PSR/DC states on i915, but the freeze persists on 6.18.The issue appeared immediately after the update, and it is 100% reproducible. I’m not running any modules that not shipped directly with Fedora’s kernel. I’m using standard i915 module provided by Fedora, with xe explicitly blacklisted after attempting to debug this issue.

I’m attaching the lspci output with hardware specs and the kernel logs for further analysis:

I would be most grateful for any assistance with this issue. As a temporary workaround, I’ve version-locked my kernel using dnf but I am concerned that 6.17 is now EOL.

Thank you for your time and help!

Word of warning - don’t rely on that version locked kernel to always be there…

See versionlock: ignored for `kernel` upgrade · Issue #2368 · rpm-software-management/dnf5 · GitHub and a discussion here

The real problem afaics seems to be the one quoted below.

This is best dealt with upstream, you thus ideally should report it here: Making sure you're not a bot! Ideally with a fresh mainline kernel, which you can get from rawhide or here Kernel Vanilla Repositories - Fedora Project Wiki
