Accidental operations caused panic on M1 iMac

Post by deinspanjer »

I was fiddling with different things trying to understand and see if I could work around some read errors on a BD disk ( Error 'Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '/BDMV/STREAM/00012.m2ts' at offset '0' repeated 30 or so times before the track is skipped).

After the disk had been loaded, I clicked the "Open Files" button on the MakeMKV Toolbar and selected the BDMV file on the disk to investigate it, but I ended up double clicking the file. The warning dialog informed me that I was probably doing the wrong thing, but the options were either to Yes (switch to reading the disk normally) or No (ignore warning and try to open the file). I didn't want either of those options, I just wanted to cancel and go back to browsing, so I hit the red X on the dialog to close it.
The computer immediately went black and rebooted. Upon reboot, I was able to see that my action had caused a kernel panic.

Here are the details from the report. Please let me know if you would like to investigate this further and need more info from me.
