I even set up Noble on my desktop to remove all the eGPU/Thunderbolt
problems. And there, this bug doesn't occur at all (even without the
fix). So I guess the issue outlined in comment #8 is somewhat hardware
specific.

Using an Intel machine is no better. At least it became clear I get the
same freezes even without the SRU installed. So I think my issues are
caused by trying to use an eGPU over Thunderbolt. We should verify this
fix on a more self-contained system with fewer variables...

False alarm?
My freezes with nouveau are just the typical nouveau repeatedly crashing
in the kernel:
kernel: nouveau :65:00.0: timer: stalled at
kernel: [ cut here ]
kernel: nouveau :65:00.0: timeout
kernel: WARNING: CPU: 7 PID: 3132 at
I don't know whether to call this a failure as the same bug, or a new
bug. I am seeing desktop freezes when the secondary GPU has a monitor
plugged into nouveau. But I can't see the original error message in the
log, so it seems like a new bug to me. Also the original bug here was a
failure to

AIUI this will only happen if there's an external monitor plugged into
the discrete GPU using nouveau. That's common, but hopefully less common
than hybrid laptops without an external monitor connected.
So as a workaround you should be able to:
1. Unplug the monitor.
2. Log in using the laptop
