Port/Peripheral information
- Peripheral vendor and name: Samsung M8 Monitor via USB-C cable
- Port the Peripheral was connected to: Tested in both USB-C ports (1,3) - issue persists across all ports

Standalone Operation
Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?
- Yes
- No
Describe the bug
After updating to BIOS 3.16, external monitors connected via USB-C completely stopped working. USB-C DisplayPort Alt Mode appears to be completely broken. Additionally, system boot time increased dramatically from ~30 seconds to over 3 minutes. The system shows critical UCSI (USB-C Connector System Software Interface) errors and AMD GPU timeouts in logs.
Steps To Reproduce
- Update Framework Laptop 13 AMD 7040 to BIOS 3.16
- Connect external monitor (Samsung M8) via USB-C cable to any USB-C port
- Monitor is not detected by system - no DisplayPort Alt Mode negotiation occurs
- Check system logs for UCSI errors
- Observe severely degraded boot performance
Expected behavior
External monitor should be detected via USB-C DisplayPort Alt Mode as it was before BIOS 3.16. Boot time should remain fast (~30 seconds).
Screenshots
System only detects internal display (eDP-1):
Monitor eDP-1 (ID 0):

[... internal display working normally ...]
All external DisplayPort outputs show "disconnected":
/sys/class/drm/card1-DP-1/status: disconnected
/sys/class/drm/card1-DP-2/status: disconnected
[... all DP ports disconnected ...]
Operating System (please complete the following information):
- OS/Distribution: Arch Linux
- Version: Rolling release (current)
- Linux Kernel Version:
Linux framework 6.16.1-arch1-1(also tested with6.12.42-1-lts- same issue)
Additional context
Timeline: Both BIOS 3.16 and kernel updates were performed while NOT connected to external monitor. Issue discovered when attempting to connect Samsung M8 monitor via USB-C afterward.
Boot Performance Regression:
Startup finished in 15.554s (firmware) + 1min 4.676s (loader) + 1min 51.875s (kernel) + 3.301s (userspace) = 3min 15.409s
Critical System Errors:
ucsi_acpi USBC000:00: unknown error 0
ucsi_acpi USBC000:00: GET_CABLE_PROPERTY failed (-5)
ucsi_acpi USBC000:00: unknown error 256

usb 5-1: device descriptor read/64, error -110/-71/-62
Troubleshooting Completed:
- ✅ BIOS reset to defaults (F9) - no improvement
- ✅ Tested Samsung M8 via USB-C on both USB-C ports - issue persists
- ✅ Tested different USB-C expansion cards - issue persists across both cards
- ✅ Verified Samsung M8 + USB-C cable work with other devices
- ✅ Tested both current and LTS kernels - confirms BIOS regression, not kernel issue
- ✅ Various kernel parameters attempted - no improvement
Technical Analysis: UCSI errors indicate BIOS 3.16 broke USB-C DisplayPort Alt Mode initialization at the firmware level. This affects core USB-C DisplayPort functionality and suggests a significant regression in BIOS 3.16.
Request: Is this a known USB-C DisplayPort Alt Mode regression? Any timeline for BIOS 3.17 to address these critical USB-C issues?
Additionally, system boot time increased dramatically from ~30 seconds to over 3 minutes.
Does that happen every time? Or just the first boot after the bios update?
Startup finished in 15.554s (firmware) + 1min 4.676s (loader) + 1min 51.875s (kernel) + 3.301s (userspace) = 3min 15.409s
Oh it's actually the kernel taking a long time, not the BIOS.
Can you upload your full dmesg log please?
Not a Framework engineer, but you might want to try resetting the EC using the following procedure:
(Ignore the quoted command, as it is not the proper way to do so).
Thanks for the response! Just to clarify after additional testing:
✅ Boot time issue is RESOLVED - after re-applying kernel 6.16.1 update, boot time returned to normal (38s)
❌ USB-C DisplayPort still completely broken - external monitor not detected on any USB-C port
Additional testing performed:
- ✅ Tested both kernel 6.16.1 and 6.12.42-LTS - external monitor broken on both kernels
- ✅ This confirms it's a BIOS 3.16 regression, not a kernel issue
- ✅ Boot time was fixed by re-applying kernel update, but USB-C DisplayPort remains broken
Current UCSI errors showing USB-C firmware failure:
ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed
amdgpu REG_WAIT timeout dcn314_dsc_pg_control
Should I downgrade the bios? If so, how do I do that?
Could you try to downgrade the BIOS to check the issue again with the same Linux kernel? If this relates to the BIOS/EC, the issue should happens on every OS.
We tried to use 3.16 with different OSs each ports work well with DP Alt mode.
How do I downgrade?
You can do it with fwupd to downgrade 3.09 or run the 3.09 EFI updater to downgrade.
Re-flashing 3.16 via EFI seemed to work. Closing this out now.
