MBP 16" Kernel Panic on 10.15.4

[swapnilsagarwal]

Hi,

I was using this all fine for over 4 months however after 15.4 catalina update the system started to reboot on waking from sleep. Somwehere it was crashing after going in deep sleep state due to a kernel panic.
After testing and switching on and off all the kernels installed. I isolated the problem to Gswitch. After disbling it now all my issues with Sleep are gone. I think app needs to be updated.
I can submit kernel panic logs if req to diagnose.

[CodySchrank]

Yes please submit the kernel panic logs.

[swapnilsagarwal]

please find attached below.

I tried safe mode and obviously it's some kind of kernel panic so does not occur there.

I wanted to figure which kernel it is. Since I have not made any change to the system in last 3 months with zero kernel panic and immediately after 15.4 there are kernel panics.

I have tried going back with Time Machine as well... on restoring to 15.3 with same setup there are no kernel panics and immediately after updating to 15.4 there are kernel panics on going to deep sleep.

I have read the Kernel log -

I have 9 extra kernels loaded almost all are well known and none related to Graphics

Little Snitch, Paragon NTFS, Turbo Boost disable, Avatron Air Display (removed now), Bongiovi DSP, Candelair IR manager (removed now so that took out 2 iospirit kext),

also removed com.cleverandson.driver.XAerial 1.0.0

Disbaling gSwicth issue went away, enabling it again it comes back. So I have shortlisted it to gswitch

I updated to 10.15.4 a few days ago and have not seen this behavior myself. Unfortunately kernel panic logs are not very helpful and if I can't reproduce the error myself I would have no idea where to start to try to fix it. This may be a new problem with the new 16", I'm not sure yet.

[swapnilsagarwal]

might be related to graphics on 16". However it was working fine from Jan till 25th March, so 2 months without any issue. I know OSX changed how it handles Kernel etc after 15.4 since a lot of apps are now broken.

All I could gather reading kernel logs was it was some kinda issue with Graphics on Mac OSX when going in deep sleep ( so happens after 4-5 hours after putting to sleep, some people are reporting issue goes away by disabling power nap feature.

[bhbitter]

I had a similar issue. Eventually I had to take my new MacBook Pro 16 to apple and they replaced the logic board. No problem since then.

[tblaschke]

I get the same kernel panics. However, even without gswitch installed. It seems that the these kernel panics are related to 10.15.4 itself and only occur when you attach usb peripherals (this includes even the usb c charger). With no peripherals I get no kernel panics.

[CodySchrank]

Thanks for the update. I will leave the thread open for now but I don't think gswitch is causing these panics.
