Thanks. I legitimately spent a sad amount of time trying to regain access to the remote board farm. Previously I could hit the bug on SM8550, but now I can't do it on SM8450, SM8350 and SM8250 (previous gens), with the same config.. I have no idea when I'll be able to get access to SM8550 again. I did test it on the QCM6490 Fairphone 5 that I initially reported this on, and neither booting next-20231010 (with your patchset applied) nor adding the below patch on top of it seems to work. I can't get serial output from this device though to find out what it's unhappy about :/ Konrad
