Summary so far: 1) Errors are found on CPU0 banks 11 and 14. 2) Errors are found during MCA timer-based polling. 3) The data is coming from MCA_DESTAT register. 4) The status bits are not consistent with documentation. 5) Likely these errors are not generating a deferred error interrupt. Bert, can you please collecting the following data? 1) Output of "/proc/interrupts". a) The MCE, MCP, THR, and DFR lines are of interest. b) We should verify if any other notification types occur besides "MCP" (MCA polling). 2) Using an older kernel, read the MCA_DESTAT registers for L3 cache. a) CPU0 bank 11: "sudo rdmsr -p 0 0xC00020b8" b) CPU0 bank 14: "sudo rdmsr -p 0 0xC00020e8" c) If these are non-zero, then I think we can confirm that the spurious data was always there.
