Kernel will send SIGBUS to program when read DE/UE, use rasdaemon to catch this SIGBUS and print it like follow:

<...>-105439 [063] 0.007348: signal_generate: 2025-03-18 14:12:05 +0800 signal: 7, errorno: 0, code: 4, comm: einj_mem_uc, pid: 105439, grp: 0, res: 0, msg: Hardware memory error consumed: action required
