I got lazy and skipped alpha1 but attempts to run alpha2 get me

Code: Select all

Did not find a cmdline Flattened Device Tree
Could not find valid device tree

What am I doing wrong?

It works with my X5000: /sys/firmware/devicetree/base

Did you load the device tree blob "cyrus-p5020.dtb" in U-Boot?

Hi All,

I compiled the latest Git kernel (alpha4) with the new PowerPC updates 5.11-1 today. Unfortunately this kernel doesn't boot on the X5000 and in a virtual e5500 QEMU machine anymore. The X1000 boots.

I was able to revert the new PowerPC updates 5.11-1 and after a new compiling, the kernel boots without any problems on my X5000.

Code: Select all

git revert 8a5be36b9303ae167468d4f5e1b3c090b9981396 -m 1

I reported this issue to the Linuxppc-dev mailing list today.

I bisected today.
