MakeMKV crashes computer on failure

[Tango]

I'm using an M2 Mac Mini, running Ventura 13.5.2. I just set this Mac up about 10 days ago, downloading the latest in a lot of software. My MakeMKV version is 1.17.4 [darwin(arm64-release] and the drive I have problems with is an Asus USB BD burner [model number here].

Overall, I'm having issues with MakeMKV handling any kind of failure. While I have settings so it will only retry 5 times, if there's a problem with reading the disk, it often stays at that one point for 5, 10, 15 minutes or more. Once MakeMKV finds a problem, I can forget ripping the rest of that disc without quitting MakeMKV and taking multiple other steps to reset. As far as I can see, the Stop button (at the end of the progress bar) is worthless if MakeMKV is stuck - that's on the problem drive and on my other drive. It works maybe once in half a dozen bad rips, if that often.

The biggest issue is with my Asus drive. (I have one other cheap drive hooked up - both are USB.) When MakeMKV encounters a problem on a disc in the Asus drive, it keeps plugging at it and won't stop. I can press the stop button, but either there's no response, or, in a minute or two, the entire computer reboots. If I quit MakeMKV to try to eject the disc and restart (or try it in another drive), my Mac still reboots. So, basically, if I put a DVD or BD in that drive, and MakeMKV can't read it all, I can expect that at some point it'll crash my entire computer.

For 6 months I was using an M1 Mac Mini, running Ventura, and, while using MakeMKV on that drive, I also experienced some system crashes. This has been the only thing I've seen actually crash macOS or OSX in at least a decade - and I've done a lot of experimenting and testing along the way.

I've included an error report my Mac provides after it reboots from one of these errors, attached below.

I want to add something to this that's not directly related to the crashing problem: If I see MakeMKV stuck at a point in reading a file, there is NO easy way to deal with it. The stop button rarely works, even if I press it and wait. (It works if I stop it when there are no drive issues, like if I realize I'm saving files to the wrong directory, but not if there's a problem reading.) If I'm lucky and MakeMKV responds by stopping reading a file, then it won't let me restart ripping to get the other files on the disc. I have to eject the disc and re-insert it and often, once that happens, I still have to quit MakeMKV and restart it if I want to continue. So even when a bad rip doesn't crash my computer, it's still quite difficult to recover from any ripping issues.

It is a little bit hard to decipher especially since so much of Apple's dump is in hexadecimal. However, the dump indicates the kernel is panicking; this is what's causing the reboot. The first line of the dump:

panic(cpu 0 caller 0xfffffe001c7c8848): IOSCSIPeripheralDeviceType05::setPowerState(0xfffffe24d9561880 : 0xfffffe001e559934, 3 -> 4) timed out after 100770 ms @IOServicePM.cpp:5604

mentions IOSCSIPeripheralDeviceType05, which is a subclass of IOSCSIMultimediaCommandsDevice. Those are the macOS classes that let a program interact with an optical drive.

My interpretation/speculation of what's happening is macOS attempts to do something with the optical drive that either fails or times out. The macOS code for the optical drive doesn't seem to have any error handling to deal with the failure/timeout allowing kernel to panic, which causes a reboot. Apple doesn't ship an optical drive with any of their computers anymore and hasn't for a while. I think the bits of macOS that interact with optical drives are slowly falling into disrepair as a consequence.

My Intel based iMac occasionally kernel panics and reboots when I'm attempting to cancel/stop MakeMKV when a drive is failing to read a disc. I find it very frustrating.

What you say about this sounds reasonable - while I've done a lot of programming in the past and still play around, I have never learned to read one of Apple's dumps like this. I did notice that nowhere in there is the actual program mentioned.

I think the bits of macOS that interact with optical drives are slowly falling into disrepair as a consequence.

(I just realized I never added the model number for the drive. For anyone following this, it's BD-RE ASUS BW-16D1X-U A105 KLEM5PG3642d, according to MakeMKV.) I find it interesting this happens with the expensive optical reader/burner and not with the cheap one. If the OS doesn't have any way to trap this problem, would it be possible to add it to MakeMKV? Overall, I feel like MakeMKV does a great job of ripping, but is very poor and dealing with anything going wrong and if avoidable, crashing an entire OS, in 2023, should be prevented if at all possible.

Last night I started ripping 2 DVDs, one in each drive, before going to sleep, and got up later to go to the bathroom and found my Mac had rebooted again, so I guess it hit a problem and timed out. But this is happening on this drive so much that, basically, if MakeMKV hits a sector it can't read, it guarantees a system crash. (I could swear it wasn't this bad last time I ripped a number of DVDs, something like 6 months or more ago.)

My Intel based iMac occasionally kernel panics and reboots when I'm attempting to cancel/stop MakeMKV when a drive is failing to read a disc. I find it very frustrating.

On the one hand, it's nice to know I'm not the only one. On the other hand, this indicates a problem. Maybe we could compare dumps and see where the issue is to recommend to MakeMKV developers something specific enough that they could easily add error trapping for any routines that use the OS functions that are crashing?

All I know is that I have three to four crashes every day on my iMac Intel 27" 2019 because MakeMKV gets stuck on the cancel button. I hit it nearly 100 times once before it finally crashed on me. I've also hit cancel "just once" and it didn't stop for 37 fucking minutes! It did stop running program scans, but just sat there like an asshole. I know I paid $60 for this schizophrenic software and I'm starting to want my money back! I update every time the developer releases one hoping whoever this developer is will FINALLY fix the CANCEL button, or cancel, or "what-the-fuck-ever" button that makes it stop! This is sickening! I waste several hours of my day babysitting this junk software because I can't trust it to run on its own.

I don't have any specific insight into how MakeMKV works. However, MakeMKV is interacting with the operating system and the firmware of the optical drive. MakeMKV does not have any control over how the OS or the firmware behave and they're probably responsible for at least some of the bad behavior here.

In any case, I take the opposite approach. I generally put a disc in the drive, set it to backup, and then stop paying attention to it. If I happen to notice things have gone really badly, I often just hit the physical button on the drive to eject the disc.

I've been trying to delete my last post-reply because I was frustrated and impulsive when I wrote it (my post-reply about the cancel button). Developer: Please accept my apologies for my outburst. It was just, "A Day." You've done very well for us and I owe you more than I actually paid.
