Changing it to probe for 0x3ca0 (PCI_DEVICE_ID_INTEL_SBRIDGE_IMC_HA0), .i.e., the 14.0 device, fixes the issue and driver loads successfully again: [ 2449.013120] EDAC DEBUG: sbridge_init: [ 2449.017029] EDAC sbridge: Seeking for: PCI ID 8086:3ca0 [ 2449.022368] EDAC DEBUG: sbridge_get_onedevice: Detected 8086:3ca0 [ 2449.028498] EDAC sbridge: Seeking for: PCI ID 8086:3ca0 [ 2449.033768] EDAC sbridge: Seeking for: PCI ID 8086:3ca8 [ 2449.039028] EDAC DEBUG: sbridge_get_onedevice: Detected 8086:3ca8 [ 2449.045155] EDAC sbridge: Seeking for: PCI ID 8086:3ca8 ... Add a debug printk while at it to be able to catch the failure in the future and dump driver version on successful load.
