Hi, I have this EXACT same issue on a system here, down to the same line number in the kernel source that throws the error.
The system is a Precision 490 workstation with 32 GB of ram, across 8 x 4GB DIMMs. Relevant log lines: [ 5.088551] loop12: detected capacity change from 0 to 32 [ 5.088762] loop11: detected capacity change from 0 to 79328 [ 5.088764] loop10: detected capacity change from 0 to 24416 [ 5.089226] loop13: detected capacity change from 0 to 27680 [ 5.673025] i5k_amb: probe of i5k_amb.0 failed with error -16 [ 5.680900] ================================================================================ [ 5.680908] UBSAN: array-index-out-of-bounds in /build/linux-hwe-5.15-AvrTps/linux-hwe-5.15-5.15.0/drivers/edac/i5000_edac.c:956:20 [ 5.680913] index 4 is out of range for type 'u16 [4]' [ 5.680916] CPU: 2 PID: 362 Comm: systemd-udevd Tainted: G I 5.15.0-119-generic #129~20.04.1-Ubuntu [ 5.680919] Hardware name: Dell Inc.
