Public bug reported:
Hardware:
- Motherboard: MSI MAG B760M MORTAR II (BIOS E7E13IMS.1A0)
- CPU: Intel Core i5-14600KF
- RAM: 32GB DDR5
- GPU: AMD Radeon RX 580 8GB
- Storage: Samsung PM9A1 NVMe 512GB
- USB sticks tested: 2 different USB 3.0 drives (e.g. SanDisk 32GB)
Ubuntu image and USB creation:
- ISO: ubuntu-24.04.4-desktop-amd64.iso (SHA256 verified)
- Tools used to create USB:
- balenaEtcher 2.1.4
- Rufus 4.13 (GPT partition scheme, UEFI (non-CSM), default settings)
- The same USB boot media works fine on my laptop (Windows 11 installed):
Ubuntu 24.04 live session starts normally and reaches the desktop.
Problem description:
On the MSI MAG B760M MORTAR II system, booting from the Ubuntu 24.04.4 live USB
always fails after GRUB:
1. GRUB menu appears and I select "Try or Install Ubuntu" (with or without
additional options).
2. The kernel starts, but shortly after I get repeated messages like:
usb 1-*: device descriptor read/64, error -71
usb 1-*: device descriptor read/64, error -110
usb 1-*: device not accepting address X, error -71
usb usb1-port*: unable to enumerate USB device
stdin: Invalid argument
3. Then it drops to an initramfs / busybox shell with:
Unable to find a medium containing a live file system
So the system cannot see the live filesystem on the USB stick, even
though the same USB boots fine on another machine.
Things I have already tried:
- Verified ISO checksum (SHA256) against Ubuntu official values.
- Used two different USB sticks and two different tools (Etcher and Rufus).
- Tried Ubuntu default boot, and edited GRUB to add:
- boot=casper
- boot=casper toram
- Tested all rear USB ports (including USB 2.0 ports) and front panel ports.
- BIOS settings (MSI Click BIOS 5):
- Boot mode: UEFI only
- Secure Boot: Disabled
- XHCI Hand-off: Enabled
- Legacy USB Support: Enabled / Auto (both tested)
- Disabled all USB 3.x ports in "USB Port Control", leaving only USB 2.0
enabled
- Removed all unnecessary USB devices (only one keyboard + the live USB).
- The system is brand new; Windows installation and USB devices work fine.
Notes:
- This looks like a compatibility issue between the Ubuntu 24.04 kernel and the
USB controller on this MSI B760 board, since the same USB stick works on
another PC.
- I plan to test Ubuntu 22.04 LTS as well to see if older kernels behave
differently.
Question:
- Is this a known issue with Ubuntu 24.04 and B760 (MSI MAG B760M MORTAR II)
USB controllers?
- Are there any recommended kernel parameters, newer kernels (HWE), or
workarounds to make the live USB detect the filesystem on this hardware?
- Do you need any additional logs (dmesg output from busybox, etc.)? I can
provide photos or copied logs.
Thank you in advance for your help.
