Comment 15 for bug 2017929

I have the same issue with -71
If I hit CTRL-ALT-DEL after the error and then hit enter it boots. (* EDIT: not if done immediately under 2 seconds)
Waiting for the 30sec timeout also works.

No AMD iGPU / APU in this system.

However my System76 Kudu6 laptop with Ryzen 9 5900HX, Radeon RX Vega 8 APU boots -71 just fine on the first try, no issue at all.

EDIT: both systems boot off a Samsung SSD 970 EVO Plus 2TB

The laptop has the AMD Cezanne iGPU/APU as the primary graphic device, connected only to the LCD panel, the nvidia RTX 3060M is the secondary GPU connected only to the external video ports and not in use at this point in the laptop's boot process.
