Comment 2 for bug 1906552

Finally managed to replicate this and confirmed it also occurs on the Pi 4 8Gb, but *only when there's no monitor attached*. Stick a monitor on it, it works (which was the reason I having troubles reproducing this). Couldn't replicate it on the CM4, but did find another issue with the latest u-boot being unable to identify the eMMC device.

Anyway, this issue turns out to be caused by the addition of PCI support to the u-boot config; disable that and everything's fine again. I'm currently prepping a trivial patch to the hirsute version (and another one to fix the aforementioned CM4 issue), which we can then SRU if I haven't managed to break something *else* in the meantime :)
