Big Sur panic when connect/disconnect usb-c dock

The problem still exists with macOS 11.4, when connect with my CalDigit USB-C Pro Dock.

Same problem for me for the last 6 months. Connecting a Dell or Belkin USB-C hub with a Dell U2718Q monitor attached (and on) make my MBP 16 2019 crash. Even switching on the Dell sometimes makes the MBP crash. I wasted hours with the Apple support. They even asked me to do a fresh install which I did and again wasted hours. Update to 11.4 didn't solve the problem.

same here. Support asked me to do a fresh install, no change. I also have a belkin USBC Thunderbold Station. Mostly will DP Cable to Monitor connected

I have a 16" 2019 MBP running Big Sur 11.4 and I'm use an HP Thunderbolt Dock G2 with my monitors connected via USB-C.

I get this all the time. Sometimes it can be all of a sudden in the middle of a session, but it is much more prevalent when I am plugging in/out of the dock. It also occurs when the laptop wakes up after being in sleep mode. I get the quick sound of the fans blowing and then it reboots. It happens way too many times. I have no other option in terms of trying other docks.

I report the error every time I get it. It has been going on since the Big Sur upgrade.

Apple, where is our support? When this issue will be resolved? The panic crash happens each day!

same issue in 11.4. well this is frustrating? Hope this can be resolved ASAP. It is crashing also every day for me..

Apple obviously doesn't fix bugs anymore but introduces new ones (like HDR video playback shows white windows on external displays). And doesn't care about it. The devices are obviously not meant to be used anymore, WLAN, Bluetooth, keyboard, screen, these are all things that should better not be used. Just like the sleep mode.

The software is too unstable, so that there are constantly problems, errors up to daily multiple kernel panics.

And instead of fixing them or at least transparently telling you that they are working on it, they just recommend you to buy new hardware or waste your life to reinstall broken software, which only frustrates you even more, because it doesn't solve any bug in Apple's software.

+1 on this 16" 2019 MBP 2.4 GHz 8-Core Intel Core i9 32GB 5600M 8 GB System ramps fans for a second then reboots when plugging in any external monitor, via a dock or EGPU. Running Big Sur 11.4 (20F71)

This only started happening after I tried booting hiveos.farm from an external USB stick, is this a zero-day / virus? Have done a clean install and restored from Time Machine, with the problem still persisting.

same here, it started from some versions ago and continue with the last one

Similar problem here. It happens when I connect to my dock, or I play with cable of external monitors. Also when the macbook pro goes to sleep then wake up, it can only detect one monitor. If I plug/unplug the cable of the other monitor, panic happens.

Been getting this since BigSur - seems to happen all the time now w/ 11.5 Beta (20G5023d) as well... frustrating because I opt'd into this to try and solve......
