Abstract
A technique for handling uncorrected memory errors (UEs) inside a kernel text section, the kernel text section being stored in a memory that is operably coupled to a CPU executing kernel program instructions. In an embodiment, a UE is detected that affects the kernel text section. The current instruction affected by the UE is identified. The UE-affected instruction is recovered by loading a copy thereof into the memory from a kernel image maintained in persistent storage. The UE-affected instruction is emulated using the copy of the UE-affected instruction. The instruction pointer of the CPU is then incremented to point to a next instruction in the memory that would normally be executed by the UE-affected instruction had there been no UE.
