AST_I2CD_INTR_STS_ARBIT_LOSS error on BMC console

Open AdrianB-Flex opened this issue 6 years ago • 0 comments

I am on the Helium branch and seeing this error semi regularly on my BMC console. Searching for this string in the repo leads to no hits. Will probably have a HW guy probe this bus but wondered what this meant exactly.
