Hi Linus,
My testing has been failing for the last few days. Last good test was with 6f2b76a4a384 and I started seeing the failure with ce840177930f5 where boot timeout.
Last good test - https://openqa.qa.codethink.co.uk/tests/323 Failing test - https://openqa.qa.codethink.co.uk/tests/335
Saw a similar issue with 5.10.79-rc1 today and bisect showed the problem with 8615ff6dd1ac but that was already in the last good test I had.
Did a bisect and this is a separate issue than the one we saw in 5.10.79-rc1.

And, indeed reverting cd7f5ca33585 on top of debe436e77c7 has fixed the problem I was seeing on my qemu test of x86_64. The qemu image is based on Ubuntu.
Will be happy to test any fix or more debugging if needed.
