Thunderbolt is working only when devices is plugged in before booting up

[scyu6058]

I have the same motherboard, same replace wifi/bt card, and an AMD 6900XT display card. I copied the latest EFI built and followed exactly all the set up (bios) as listed in your post. I can only get TB4 working when the device (an NVME drive) is plugged in the TB4 port before the system was started up. Hotplug was not supported. THe device was not detected during a warm boot. My NVME showed up as hightlighted under the PCI tab in system info. Any enlightenment ?

?

Hey @scyu6058

here is the config I am currently using. TB Hotplug is working.

I also have 6900XT AMD display card. I copied your EFI abd booed up the system. Everything worked fine except TB hotplug did not support my NVME external TB3 drive. The drive was detected Upton cold boot. I ejected the drive and re-connected it back but the drive did not show up. Just don't know why.

@scyu6058 I don't know. Thunderbolt is an inconsistent bitch. Now it is also not working for me anymore. I even tried going back to Big Sur and used my config zipped as "EFI_best yet_TBHP working", which I normally do when things get working to freeze this state.

Funny thing is, now sleep is working and TB devices are getting detected after sleep. Before it was the opposite: Sleep was breaking TB-link. But hotplug was working before sleep. And I didn't change the TB-config after it was working.

I think it also has side-effects when you are using TB with Windows as well. E.g. Sometimes macOS doesn't detect my TB-SSD. But after one Windows boot, macOS is detecting it again.

On my Thunderbolt Dock I have a blue light which is indicating if TB is on or not. And I noticed that even after switching between Windows and Mac, the TB light is not flashing which to me indicates that the TB-link is staying active while rebooting and switching between macOS and Windows even with the SSDTs in between.

And when I disable Thunderbolt in BIOS, I have to Reset to Defaults to get the Thunderbolt Submenu again to enable it again.

I think I just call it a day and don't spend any more hour in trying to get Thunderbolt Mystery solved. I have spent way over 100h to get it done. Specially on this Board with this BIOS, where it seems not to be done right by Gigabyte or just good enough for Windows.

Actually I did not boot into windows in my dual os setup. And my TB device’s light was always on.

Anyway, thanks for your assistance. TB is really a bitch. I followed your post just for interest’s sake and I hate the behaviour is always changing.

Thanks.

Not sure if anyone is having these issues still, did you guys try downgrading your bios version to f7? That helped solve thunderbolt issues for these people (linked below). @SchmockLord could this be why you had to disable your Thunderbolt SSDTs a week ago?

@drewbk99 Yeah, could be. Thanks for the hint. Will try that.
