I have also a similar problem running redpanda, because redpanda uses seastar code and seastar assumes there are a 48 bit virtual addresses.

IMHO the right request is to enable CONFIG_ARM64_VA_BITS_48. In bcm2711_defconfig nor bcmrpi3_defconfig is not defined so the default is CONFIG_ARM64_VA_BITS_39=y. On defconfig is enabled. The CONFIG_PGTABLE_LEVELS param is not configurable...

I recompiled the kernel with CONFIG_ARM64_VA_BITS_48 = y. It works. I am currently testing it as a kubernetes worker node (k8s 1.21.1, containerd 1.4.4), with raspbian os 32 bit, armv8...

Both ubuntu and debian have this configuration enabled for raspberry 3 and 4. This means that all existing packages that assume this configuration cannot run on raspberry pi OS. Typically...
