Yesterday, my iMacPro crashed every couple of minutes. Disconnected external monitors, everything stable.

@Apple: This bug is super-annyoing, and needs to be fixed ASAP. It renders an expensive machine useless...

userspace watchdog timeout: no successful checkins from com.apple.remoted in 180 seconds
...

I have the same troubles for a while also since Big Sur is coming… Three times today!

panic(cpu 2 caller 0xffffff8009f64a25): 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 wake (15530 seconds ago): 1542, last successful checkin: 120 seconds ago

iMac 21" Retina 4K 8GB RAM 2400 Mhz DDR4 (2017)

1. Ghz Quad Core Intel i5

Radeon Pro 560 4GB

Any help possible or just waiting for an Apple Big Sur update/bugfix?

Same same -- iMac shuts down at least once daily. We have two users set up on this machine:
Big Sur v11.2.3
iMac (Retina 5K, 27-inch, 2017)

1. GHz Quad-Core Intel Core i7

64 GB 2400 MHz DDR4
Radeon Pro 580 8 GB

I've reset the SMC and PRAM with absolutely no positive effect.

The fact that this has been going on for so long without any mention of an issue or fix from Apple is pretty bad -- you've taken a big reputational hit ...

Received the same error couple of times in my new MacMini M1 (2020), 16GB Memory, 2TB HDD. I was having time machine backup and connected to 2 4K external monitors. Need a fix for this:

I am having the same problem since upgrading to Big Sur. I am on MacBook Pro (16-inch, 2019, 64 GB. 2,3 GHz 8-Core Intel Core i9.AMD Radeon Pro 5500M 8 GB / Intel UHD Graphics 630 1536 MB). When I disable the automatic graphic switching it gets a little better but I have to reset the Mac 2/3 times a day . I am using just Zoom/Slack/Safari. What´s going on?

I've removed the Soundflower kext and my issues with the com.apple.firehose.io-wl panics seems to be solved...

Same issue. Every two days I'm presented with a rebooted iMac in the morning. 1 external drive for Time Machine and a Fujitsu IX500 scanner attached. This has been happening under Big Sur for many months.

I've having the exact same problem. It happens every 2 to 7 days, but at least once a week. It started with the Big Sur OS installation. Never had a problem before upgrading to that OS. ASeems every OS Apple releases, whether on a laptop or phone is bugged to the point it shouldn't have been released.

This system crasher has been here for months. It needs fixed yesterday. Sincerely question whether quality is something Apple cares about these days, much less prides itself on.

Code Block 
panic(cpu 4 caller 0xffffff8006d64a25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds

Ditto, what was a hugely stable iMac Pro, after upgrade to Big Sur now seems to reboot sporadically.

Typically opaque Apple response ... crickets.

I hope everyone is sending Apple the crash report after rebooting - I am.

So, I was having this really frustrating issue with my iMac Retina 5K 4 GHz Quad-Core Intel Core i7 after I upgraded to Big Sur, it would crash randomly about 10 times a day. After days and days researching without success I finally stumbled upon a list of easy fixes you can try, including resetting your Mac's NVRAM, which I did. It's been 3 days and no crashes yet. Some of you might have done this already, but for those of you who haven't, this might be the solution you were looking for.

The list of easy fixes was posted by Michael ****** in his website and it's called "The Top 11 Tricks to Fix Common Mac Problems Quickly".

I might add that along with this I also cleared all the caches and deleted some apps I even forgot I had.

Hope this helps someone.

Same issue here...randomly restarts at night.

Same here: macpro late 2013, sometimes 3x times a day, sometimes once in a week
crashes only if am not working on the computer

Same issue here, apparently. Computer starts crawling to a halt after "heavy" usage (any video app, for instance, or Music, or Office Apps). Either that or reboots after a few minutes when trying to wake up. And OneDrive always crashes. And indexing NEVER stops. I've got a second screen on Thunderbolt and external HDs through USB.
