vexpress64.conf is missing some key CONFIGs about Regulators, which cause the kernel to complain about mmc voltages, and panic.
These additional configs seem to help.
Which kernel tree, config (android/ubuntu/ubuntu-minimal?), root filesystem (Android/OE?), RTSM and device-tree are you using?
I am using linux-linaro branch of linux-linaro-tracking tree: ubuntu-minimal for OE rootfs, RTSM and rtsm_ve-aemv8a.dts. Without these configs, I get mmc errors; I stumbled upon an old bug report where you had suggested.
I don't doubt that these are probably needed (they are for 32-bit vexpress) but am wondering why we haven't seen this problem before.
Thanks
