After updating to macOS 11, aka Big Sur, my Mac has kept crashing every ~2 hours. Here's the kernel panic log from one recent panic
Here is another panic log.
I initially thought the issue was related to a Dell DisplayLink docking station I had connected to, but I have uninstalled the driver and I have also experienced crashes without any peripherals attached.
Any help reading and understanding a kernel panic log would be much appreciated.
I should note that the install process of big sur was a bit strange with several reboots and clicking "update" again. Not sure if that means anything.
I'm on a 2017 15" MacBook Pro with touchpad, i7 and intel graphics.

Your panics repeatedly occur in
IOAcceleratorFamily, which is the graphics driver. Panics with this specific signature are overwhelmingly the result of a bug in macOS, not anything that you’re doing wrong. Debugging this fully requires Apple internal tools and engineering expertise, not to mention access to the code. You won’t be able to fix this yourself (although you might stumble upon a workaround, such as a full erase-install) because this isn’t the user’s fault.Your best bet is to file a bug report and provide Apple with detailed information to help reproduce and root-cause your issue. This will include collecting a
sysdiagnoseimmediately after you reboot from a crash ($ sysdiagnosein Terminal or CommandOptionControlShift. from any app). Then you can file the bug via the Apple Developer bug reporter if you have a developer account or through Feedback Assistant if you don’t. If you file a good report, you will either work indirectly with an Apple engineer if this is a novel bug or have your data be added to the pool of existing reports for this same issue. Apple will then work to make a fix and roll it into the earliest software update that it can.
