60 Single Machine Check Error May Report Overflow

Description

A single parity error encountered in the data cache tag array may incorrectly report the detection of

multiple errors, as indicated by the overflow bit of the DC Machine Check Status register (bit 62 of

MSR 0x401).

Potential Effect on System

System software may be informed of a machine check overflow when only a single error was actually

encountered.

Suggested Workaround

Do not rely on the state of the OVER bit in the DC Machine Check Status register.
