Cable Unplugged in Monterey

[THLIVSQAZ]

mac version: 12.0.1(21A559)
ethernet card :

problem:


kextLoad:

system is new install ,not OTA upgrade from big sur
I also try to install to /L/E and disable sip ,switch the speed ,deleted and reseted preference ,all not working

network status led on router and motherboard is working, if I use command "sudo ifconfig en0 down" the leds is off , and use "sudo ifconfig en0 up" is on

i didn't found the log in log show and /var/log/system.log, so i take photo when boot up

Most likely an interrupt related issue but I have no time to investigate it at the moment.

[THLIVSQAZ]

I see ，thinks

In monterey 12.2.1 with kext v.2.4.2 it work great.
But it's a pcie card, not onboard nic. Monterey have been hard with all onboard nic.
Thanks meize!

I'm trying to debug now and seems that interruptOccurredPoll doesn't debuglog blah blah blah at all in 12.3, maybe msiIndex is wrong?

In 10.15 every 1 second i see logging from dmesg

[Benau]

Maybe 12.3 handles

    while ((intrResult = pciDevice->getInterruptType(intrIndex, &intrType)) == kIOReturnSuccess) {
        if (intrType & kIOInterruptTypePCIMessaged){
            msiIndex = intrIndex;
            break;
        }
        intrIndex++;
    }

differently, maybe some new (fake!) devices will break eariler

[Benau]

BTW it seems that intrType & kIOInterruptTypePCIMessaged is true for 1 2 3 4 with my onboard lan too
In Benau@fcd42d6, I manually 'poll' interrupt and it seems to work fine with both rxPoll on / off, @THLIVSQAZ can you try this Kext and see if it works? (and does my commit make sense, I'm a noob kernel programmer)

@Benau happy to report that your driver change actually fixed my on-board card.

Nice!

@Mieze can you see if my commit make sense for you? Or do you have a better idea instead of keep polling the card every 1ms?

BTW even changing msiindex to 2, 3 or 4 still doesn't work

Thank you so much for making this kext available. Fitting also solved my problem here. Thanks.

This kext file works really well for AMD Ryzen 3 3200G. Been struggling since couple of days. Thanks :) Should release this patch as many are facing this issue.

@Benau (cc @Mieze) I can also approve that fix works (at least at first glance)! Please consider to review and pull the changes

[Mieze]

If the driver is unable to pick up the matching interrupt, that's clearly an ACPI related problem and problems should be solved at the origin. I know, macOS is becoming more picky on that with every release but that's not my fault. Permanently polling the device makes no sense and I'm not willing to integrate such a patch.

[blacksd]

@Mieze I understand that this patch is not a solution, and should not be merged, but shall we keep this issue open - at least as to have a proper place to look for another solution and/or make people aware of the current limitation?

[adrianlungu]

Unfortunately, I tried the kext from @Benau on my end but it didn't want to budge. Still getting cable unplugged.

Tried other versions of the kext as well and it was a no go.

I'm not sure what to go for SSDT-wise, but I'm open to any suggestions to get this working!

Update: got some help on Reddit and apparently I had DisableIoMapper set to false which caused this issue to occur. After enabling it, ethernet started working as expected.

You soled my issue (and probably many other's people issues too).

You rock!
