I booted the 6.12.38 kernel using the kernel parameter "usbcore.nousb". The 6.12.38 kernel did not successfully boot. I would suspect that the USB message is not an indicator of the cause of the boot hang.On 30/07/2025 at 15:02, Ricardo Muggli wrote:When I choose "Debian GNU/Linux, with Linux 6.12.38+deb13-amd64 (recovery mode)" it hangs during the kernel boot at this message: 1.978505 usb 3-4: new high-speed USB device number 2 using xhci_hcd It doesn't get to a login prompt.So it looks like the ACPI messages were a red herring. This message may be a red herring too, but it is worth checking if this USB device is actually involved. You can boot with kernel 6.12.33 and try to identify the USB device and its driver with the following commands: lsusb -vt dmesg|grep "usb 3-4" # as root or with sudo
I then looked in dmesg from the 6.12.33 kernel and noticed that "xe" would be the next thing that would show up. I booted the 6.12.38 kernel using the kernel parameter "modprobe.blacklist=xe". The kernel booted and I was able to login. The graphics of course were degraded.
If there is anything I can do to assist in identifying the root cause, please let me know.
