Decode kernel panic, Ventura

Is there a way to tell is this is a hardware or software-based issue?

The LLC (Last Level Cache) Bus Error suggests a problem with the communication between the CPU and its cache hierarchy (likely L2 or L3 cache). The command acc_cifl2c_cmd_rd_ld indicates a read-load operation from cache, suggesting the CPU attempted to read from a cache line that caused the fault. Although this panic could be hardware (CPU / RAM) related, it could also be caused by a faulty device driver / kernel extension (kext.)


The other place to look in this report is the last started kernel extension (kext):

  • Last started kext: com.apple.UVCService (handles USB Video Class devices, e.g., webcams). If you recently connected or used a webcam or another UVC-compliant device, it could have triggered the issue.
  • Last stopped kext: com.apple.filesystems.exfat (for exFAT drives). If you had an exFAT-formatted external drive connected, it could also cause instability if there are disk issues.
  • Loaded kext: com.focusrite.driver.FocusritePCIe (audio interface driver). Audio interface drivers, especially for PCIe, can sometimes conflict with system resources or fail under heavy load.

All great points. Removed Focusrite PCIe only using an interface via Avid HDX in a Sonnet Chassis. No ExFat drives connected to the system, so that is curious. I am using the OWC dual HDMI adapter that required the DisplayLink software to work properly, so another potential. Will report back if killing the Focusrite PCIe does it!
