Decode kernel panic, Ventura

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.

Nice analysis.

There is also the kext com.digidesign.iokit.DigiDal - which is for a 16 channel digital audio interface. It could also be the source of the problem, or it could be conflicting with com.focusrite.driver.FocusritePCIe.

Good point!
