Can you share more details about your machine and setup? Are you using a dock, and if so which brand/model? What about your monitor? Are the crashes happening when you connect or disconnect the monitor? Are you connecting it via HDMI or DisplayPort?

If only Apple would bother porting the fix back to Big Sur for those who can't upgrade... my work laptop usually lags behind the latest release by 6 months as it takes a lot of time for my company to test and certify all corporate software.

Your crash report is slightly different: "Kernel trap at...". Most of the reports in this thread are "element modified after free", so your issue might not be the same.

Are you connecting with DisplayPort. If so, try using a USB-C to HDMI instead. The issue in my case was exclusively affecting DisplayPort connections.

Does your monitor support HDMI? If so I'd suggest trying a USB-C to HDMI cable. That's fixed the issue for me.

Upgrading your docking station is unlikely to make any difference. In fact, you're likely to get kernel panics even if you connect your monitor directly to your laptop (and not through a docking station). If you're using a DisplayPort connection I'd suggest trying a USB-C to HDMI cable instead - this did the trick for me. Also, if your monitor supports it, disabling DisplayPort 1.2 also fixed the issue in my case.

Have you tried connecting the monitor with a USB-C to HDMI cable? Avoid plugging it in through a dock/adapter. Also, check if your monitor can be setup to use DisplayPort 1.1. My Dell monitor uses DP 1.2 by default but it can be disabled via the monitor on-screen menu -> Display -> DP 1.2 -> Disable. Once I turned off DP 1.2 I never had another crash.

Does your crash report says "element modified after free"? Big Sur 11.5 was only released on July 21st. Were you running a beta release? Were you experiencing panics on previous MacOS versions?

That is such a lame response from Apple. I can easily crash my top-of-the-line MacBook Pro with a simple USB-C/DisplayPort cable. How can that be a third party issue? And even if it was a third-party issue, the fact an operating system can be so easily trashed by a third-party device and they won't do anything about it is just really bad customer service. In my company (12,500+ employees worldwide) almost everyday there's someone in the public IT support Slack channel complaining their shiny new laptop is crashing. The IT guys are shocked and completely overwhelmed with the number of issues with the latest model.

@nguerreiro, are you connecting monitors via HDMI or DisplayPort?

@gurucc when you're using HDMI, are you using a USB-C/HDMI cable or are you using a dock/hub/adapter?

Interesting... will Apple bother to port the fix back to Bir Sur, I wonder!

@DelGurth, my MBP also has AMD Radeon Pro 5500M. Did you test it with an Apple display? Which one? Maybe this issue is only affecting non-Apple monitors. I have 2 Dell monitors, and both can crash my laptop.

In my case it only crashes when using a DisplayPort connection, and never with HDMI
