skiboot 6.0.2 was released on Friday May 18th, 2018. It replaces skiboot-6.0.1 as the current stable release in the 6.0.x series.
It is recommended that 6.0.2 be used instead of any previous 6.0.x version.
Over skiboot-6.0.1, we one bug fix:
cpu: Clear PCR SPR in opal_reinit_cpus()
Currently if Linux boots with a non-zero PCR, things can go bad where some early userspace programs can take illegal instructions. This is being fixed in Linux, but in the mean time, we should cleanup in skiboot also.
This could exhibit itself as petitboot getting killed with SIGILL and no boot devices showing up, but only in a situation where you’ve done a kdump from a kernel running a p8 compat guest
