Sorry about the 3rd party KEXTs, but it really is the best way ahead if they’re potentially causing panics. I didn’t get a log to capture or to send to Apple. This identifies all the kexts which are referenced in the backtrace above, and gives you a more useful shortlist of those which should be suspected as being involved in the panic. @plugin.IOgPTPPlugin 840.3 What are the panic logs reporting as the cause? – z0nam May 29 '20 at 1:27. This gives the Model Identifier, and states whether the system had been preparing to shut down. I’m wondering, though, if it was the same issue, and I just happened to notice it in time, so I was able to restart the Mac before the kernel panic would have happened otherwise. I look forward to that, and as always extend my thanks for your informative and enjoyable work. panic(cpu 1 caller 0xffffff7f8af6fad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds Note that those are unlikely to coincide with the kexts identified earlier as possible culprits, so you’ve got more to add to your list. Didn’t figure it would solve anything but at least get the problem in the system. Howard. Making me think, that Catalina updated a firmware on the GPU or else, which won’t be reverted when downgrading to Mojave. Are you getting kernel panics? Howard. |IOSCSIBlockCommandsDevice 422.120.3 At least I’ve been seeing it on my (un-supported I know) Mac Pro (Mid 2010) since I put Catalina on it at version 10.15.2 and it happens after waking from sleep from time to time, but I’ve also seen it panic during boot. 03:45:36.684302+0100 kernel CoreAnalyticsFamily virtual bool CoreAnalyticsUserClient::initWithTask(task_t, void *, UInt32, OSDictionary *)::165:success !UXHCIPCI 1.2 >!AVirtIO 1.0 My MacBookPro just hangs up and restart whenever I leave it running for days since the upgrade to 10.15.6. @z0nam Good to hear! The first panic is the same as you mention in this issue, maybe it is not a itlwm bug but related to Apple's Airport, I don't know what is going on, the Apple Airport framework crash on init state. >!AThunderboltDPOutAdapter 6.2.6 0xffffff911ac0b720 : 0xffffff8009d1a65d >usb. About the only thing I was still able to do was to log in via ssh from my MacBook Pro and issue a “sudo shutdown -r now”. |IOUSBHost!F 1.2 03:21:12.314761+0100 osanalyticshelper Attempting to write jetsam report
