skiboot-5.3.4 was released on Tuesday September 13th, 2016.
This is the 5th stable release of skiboot 5.3, the new stable release of skiboot (first released with 5.3.0 on August 2nd, 2016).
Skiboot 5.3.4 replaces skiboot-5.3.3 as the current stable version. It contains a couple of bug fixes, specifically around failing XSCOMs.
Over skiboot-5.3.3, the following fixes are included:
xscom: Initialize the data to a known value in xscom_read In case of error, don’t leave the data random. It helps debugging when the user fails to check the error code. This happens due to a bug in the PRD wrapper app.
xscom: Map all HMER status codes to OPAL errors
centaur: Mark centaur offline after 10 consecutive access errors This avoids spamming the logs when the centaur is dead and PRD constantly tries to access it
nvlink: Fix bad PE number check in error inject code path (<= rather than <)
