An issue was found on the HiFive Unmatched with the 5.19-rc1 kernel. The
following warning occurs during boot:

riscv64 kernel:
----------------------------------------------------------------
riscv64 kernel: WARNING: Missing the following errata may cause
potential issues
riscv64 kernel:         SiFive Errata[0]:cip-453
riscv64 kernel:         SiFive Errata[1]:cip-1200
riscv64 kernel: Please enable the corresponding Kconfig to apply them
riscv64 kernel:
----------------------------------------------------------------

I've manually bisected the problem to this commit:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ff689fd21cb13098305bae3f8d0c0065df2e2fc1
