With the upgrade to Big Sur 11.0.1, my iMac Retina 4K 6-core intel core i7 has become highly unstable. Its crashed 4 times in the last 6 hours. 2 times it crashed with no report. The last 2 times I received a report. The odd thing is one time it crashed when I wasn't even using the computer. This time it crashed with Android studio open, safari open, the app store open, and amazon music playing. Otherwise, I wasn't using the computer. I used to brag to my friends how stable and secure MacOS was. Not quite sure with this release. Any suggestions? panic(cpu 4 caller 0xffffff801dd53a13): userspace watchdog timeout: no successful checkins from com.apple.logd in 120 seconds service returned not alive with context : unresponsive dispatch queue(s): com.apple.firehose.io-wl service: com.apple.logd, total successful checkins since load (7120 seconds ago): 701, last successful checkin: 120 seconds ago service: com.apple.WindowServer, total successful checkins since load (7090 seconds ago): 709, last successful checkin: 0 seconds ago
