Seeing the same thing when I dock/undock. The TouchBar often flashes/flickers before the crash happens if I'm working on the laptop after undocking. I send a report into Apple each time (example below). Happens 2 to 5 times in a row before stabilizing. The error message changes a little each time (example below - often has "Sleep/Wake hang detected"). Send into Apple every time. Dell thunderbolt dock and Sabren monitor adapter with 2 monitors running. OS 12.6 on a 2020 13-inch MacBook Pro with Intel i7. Is there a workaround for this? Are Apple developers monitoring this site and is there a fix coming at some stage? Are there any docks that work? Is it a dock issue or is it related to transferring from laptop monitor to external monitors? panic(cpu 1 caller 0xfffffff028ce6bac): Sleep/Wake hang detected @IOPMrootDomain.cpp:12600 Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 19P6066 macOS version: 21G83 Kernel version: Darwin Kernel Version 21.6.0: Wed Aug 10 14:04:32 PDT 2022; root:xnu-8020.141.5~1/RELEASE_ARM64_T8010 Kernel UUID: ED0C23DC-B156-3B2D-A95D-022856D12AD5 iBoot version: iBoot-7459.141.1 secure boot?: YES x86 EFI Boot State: 0x16 x86 System State: 0x1 x86 Power State: 0x1 x86 Shutdown Cause: 0x5 x86 Previous Power Transitions: 0x100010001 PCIeUp link state: not available Paniclog version: 13 Kernel slide:   0x0000000020f48000 Kernel text base: 0xfffffff027f4c000 mach_absolute_time: 0x1ed7308843a Epoch Time:    sec    usec  Boot  : 0x62fdad8e 0x0007708f  Sleep  : 0x62fdbea5 0x0006bd8b  Wake  : 0x62fdc2b1 0x000ac305  Calendar: 0x62ff0d66 0x000916ac Zone info:  Zone map: 0xffffffe036df4000 - 0xffffffe636df4000  .

Exactly the same thing happening to me. I use a Dell dock and two monitors.
