@singhalrishi27

• Does it trigger a kernel panic? If so please attach the panic logs.
• Does it crash if itlwm.kext is used instead?
• Have you tried to reset the network interfaces? (instructions can be found in the docs)

Thanks.

Unfortunately I didn’t purchase this service and it is unavailable in the county zxystd lives in so it’s not very convenient for us to verify. If others are facing the same issue feel free to share them below.

[singhalrishi27]

Thanks.

2.)nope not tested with heliport
3.)yes I even reinstalled macOS

[zxystd]

@singhalrishi27 Hi, thank you for reporting this issue, can you please add keepsyms=1 to boot-args then reproduce the issue again? I think it is an airport related issue.

[singhalrishi27]

@singhalrishi27 Hi, thank you for reporting this issue, can you please add keepsyms=1 to boot-args then reproduce the issue again? I think it is an airport related issue.

Do I have to use debug kexts?
And you need panic logs or kext log?

[zxystd]

@singhalrishi27 yes, debug kext is needed. panic logs, kext logs would be well if possible to get that.

[williambj1]

All alpha version kexts are built with debug features enabled.

Missed the button...

[singhalrishi27]

@zxystd Hey I was able to collect a lot of logs for you.
What I did -
installed latest alpha kext
added Debug Enhancer.kext
added keepsyms=1 to boot-args
Took Clean Snapshot of config.plist
and restarted macOS
after that, I started collecting logs when everything was working after some time itlwm crashed

Screen.Recording.2022-01-05.at.11.40.40.AM.mov

in this clip, you can see that I can't turn off wifi
also, network preferences is empty
after a while macos crashes
from crash I mean macOS stuck at just one screen no inputs works like trackpad will do nothing you can't move your cursor etc you have to force restart your Laptop I'm attaching a log in a separate comment...

Immediately when the issue starts, put your mac to sleep (wait for the indicator light to show it's sleeping), then wake it back up. Attach the logs after the wake. Did it fix the wifi?

Nope it doesn't after wake system becomes unresponsive after a while and you have to force restart it after that same log message appears and asks me to send report to apple

Consider trying itlwm.kext with HeliPort?

[zxystd]

Any other way we can fix it?

@singhalrishi27 Still doing research, but from what I received the similar issues have the common thing that they all using macOS 12, so can you help me tested on BigSur or Catalina? or can you use Heliport for test?
Thanks a lot.

@williambj1
@zxystd
i tried with heliport and issue still remains.
After a while Heliport will crash in activity moniter heliport will not respond.
if you force quit heliport
it will take 30 seconds just to foce quit the app after force quitting Helipot macOS will crash

@singhalrishi27 Interesting results and thank you for testing. Does Ethernet work fine with the private relay?

[singhalrishi27]

@singhalrishi27 Interesting results and thank you for testing. Does Ethernet work fine with the private relay?

I don't have ethernet in india we mostly use cellular 😅 btw change the tag from question to a bug

At this point it still unclear whether there is a bug in Safari/private relay shipped in macOS Monterey or the issue is directly related to itlwm. Theoretically, user space software (in this case, a browser + a proxy) should not be able to trigger kernel level crashes if another other ways of browsing the internet works fine.

We have quite a lot of people using Monterey in our internal testing group and so far I haven't heard of any similar crashes; a few people are using the same wifi card and version of os as yours. However we've recently got in touch with the author of #735 which also have a very similar crash but that person uses a different wifi card.

Test results from other network adapters will help a lot. If Ethernet is not available, sharing the network from a phone can also do the trick.

@williambj1
You are right first i thought private relay is in beta so might not be stable but likely impossible a service can occur kernel panic i will try with ethernet then I will tell you what happens.
My Uncle has a real mac he uses private relay and it works just as well as not using private relay. Hope i somehow manages to get hands on with someone else's ethernet and will try to produce the issue

[singhalrishi27]

@williambj1 @zxystd i tested with ethernet private relay works surprisingly well with it. I can confirm that the issue is indeed with airportitlwm and itlwm🥲

[zxystd]

can you check if the v2.2.0-alpha have the same panic? I don't see anyone reported the same panic yet.

[singhalrishi27]

Yup issue still exists

[zxystd]

@singhalrishi27 O, can you also try connecting to an open wifi which means no encryptions to see if the issue still persist? Or try to use another router if you can.

I have the exact same issue with private relay running the latest 2.2 alpha kext on Monterey. Lenovo T480 Intel 8265 card. With private relay off - everything works rock solid.
