I'm running Big Sur 11.1 and I have the same issue as well. I recently reinstalled the OS (not a clean install but just the OS via Repair Mode), thinking that would fix it. But just crashed again. panic(cpu 6 caller 0xffffff800356ea25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds service: com.apple.logd, total successful checkins since wake (230 seconds ago): 24, last successful checkin: 0 seconds ago service: com.apple.WindowServer, total successful checkins since wake (230 seconds ago): 12, last successful checkin: 120 seconds ago service: com.apple.remoted, total successful checkins since wake (230 seconds ago): 24, last successful checkin: 0 seconds ago Backtrace (CPU 6), Frame : Return Address 0xffffffc1b5803670 : 0xffffff80002b9aed 0xffffffc1b58036c0 : 0xffffff80003fc6e3 0xffffffc1b5803700 : 0xffffff80003ecd1a 0xffffffc1b5803750 : 0xffffff800025ea2f 0xffffffc1b5803770 : 0xffffff80002b938d 0xffffffc1b5803890 : 0xffffff80002b9678 0xffffffc1b5803900 : 0xffffff8000abe434 0xffffffc1b5803970 : 0xffffff800356ea25 0xffffffc1b5803980 : 0xffffff800356e678 0xffffffc1b58039a0 : 0xffffff8000a4569e 0xffffffc1b58039f0 : 0xffffff800356dab4 0xffffffc1b5803b20 : 0xffffff8000a4f86b 0xffffffc1b5803c80 : 0xffffff80003a7d81 0xffffffc1b5803d90 : 0xffffff80002bf0e7 0xffffffc1b5803e00 : 0xffffff8000295905 0xffffffc1b5803e60 : 0xffffff80002ad012 0xffffffc1b5803ef0 : 0xffffff80003d0ec3 0xffffffc1b5803fa0 : 0xffffff800025f216 Kernel Extensions in backtrace: com.apple.driver.watchdog(1.0)[7AE04EA4-D026-39A0-B2D5-5C9E4EE72967]@0xffffff800356d000->0xffffff800356efff Process name corresponding to current thread: watchdogd Mac OS version: 20C69 Kernel version: Darwin Kernel Version 20.2.0: Wed Dec 2 20:39:59 PST 2020;
