Abstract
A system, method and apparatus to record data relevant to hardware errors identified by microprocessors. For example, in response to a hardware error, a microprocessor can store first data about the error in registers in the microprocessor and start to execute instructions configured in firmware and/or in an operating system. Execution of the instructions in response to the hardware error causes the microprocessor to: generating second data about the error based at least in part on the first data in the registers; and store the second data at a location not affected by restarting execution of an operating system in the processor. For example, the execution of the instructions can cause the microprocessor to decode the first data to obtain a temperature of the computing device as part of the second data.
