BugLink: https://bugs.launchpad.net/bugs/1967130 When booting with EFI, VMAP_STACK causes CPU stalls. Disable this config option, until a fix exists that allows using VMAP_STACK together with EFI. VMAP_STACK on RISC-V was first added in v5.14 kernels, thus this option has not yet shipped in any stable series. EFI support is new in Jammy as well.
