Created attachment 307434 [details] dmesg output A new installation of Fedora 41 on a Thinkpad T15g has resulted in no ability to use the Wifi. Installing F39 did work, as well as does the Windows 11 on dual boot. The device is listed as hardware but dmesg (attached) contains error -110, meaning it doesn't show up on rfkill or nmcli. inxi reports: Network: Device-1: Intel Comet Lake PCH CNVi WiFi driver: N/A bus-ID: 00:14.3 chip-ID: 8086:06f0 I have turned off fast boot in Windows as per instructions and after searching on Bugzilla. As far as my initial investigations go, it looks like there is something not working in the newer kernel with this device. Happy to switch on debug and assist investigation. Have linked to another bug report that looked similar...?
Can you do a power off/on cycle and check if it works?
If that still doesn't help, please try this: > Eventually what helped was to shut down the machine and keeping the power > button pressed for 30s with battery removed: > https://www.reddit.com/r/techsupport/comments/12nyre/30_second_power_button_trick/
This looks similar to bug 209641

(In reply to Artem S. Tashkinov from comment #3) > This looks similar to bug 209641 Thanks! :) I didn't find issue that in my search for error -110, apologies. I will try the power drain method, cycling does not work, and get back to you after reviewing that thread.
(In reply to Artem S. Tashkinov from comment #3) > This looks similar to bug 209641 In the case of the T15, I disconnected the in-built battery via the BIOS (without physical removal) and undertook the 30s power hold as well. This appears to have worked, I've got wifi for the first time on this kernel version. I have also, following the above referenced bug, added the reset on the device for modprobe loading of iwlwifi. I'll keep an eye on this and determine how the operation of the driver goes with these two solutions in place. Happy to replicate this issue if need be, but it's windows innit. ;) Many thanks indeed.
Emmanuel, Is there any particular reason why this issue that was first reported more than five years ago, is still unresolved?
At the very list it must be documented I guess. So instead of spitting out error -110 the kernel could have admitted the device state is borked in Windows and it needs to be properly reset.
Sounds like a plan. The difficulty for me was in knowing where -110 is referenced, though I admit I didn't look in the kernel source Will have a look and propose a patch, if that'd be of help!?

Probably you should discuss your idea with them first in the Linux wireless mailing list.
Can you please check if you have AMT enabled? can you please reproduce with debug=0xf? Thanks!
ping?
Apologies Emmanuel, haven't had an opportunity to look into either AMT or the debug=0xf. Can I ask the benefit to doing either of these things prior to undertaking them? I'm a bit time poor ;) The wifi is now pretty stable, barring the occasional (usual?) issue when starting up from a sleep / hibernate, though that's not often. Therefore the previously mentioned fixes seem to have helped. However, happy to try and find time to reach out to the wifi developers (if you're not one) to talk about more informative patches and / or reproduce the error if worthwhile. Nice one :) James On 11/05/2025 10:30, bugzilla-daemon@kernel.org wrote: > https://bugzilla.kernel.org/show_bug.cgi?id=219651 > > --- Comment #12 from Emmanuel Grumbach (emmanuel.grumbach@intel.com) --- > ping? >
No need to apologize. We're trying to pay more attention to the bugzilla db. If I understand correctly, there isn't much we can to help you here, so I guess the right course of action would be to close this ticket? If you agree, I'll do just that. You can always reopen it, and I'll be notified about any new comment you add here even if the ticket is closed.
Created attachment 308131 [details] attachment-9943-0.html Ah nice! I think the only possible take forward from this was a potential patch to make error -110 more descriptive in logging. I would be happy to look at that but, as you say, this ticket should probably close and that happen independently. I would be interested to hear your thought on adding a message to notify users of an unclean device shutdown though.

Well, I think we go have error prints when things don't go as expected. What do you mean by unclean device shutdown. In your case the probe went wrong.
Created attachment 308141 [details] iwlwifi_error.txt Hi Emmanuel So the wifi stopped working after a restart, with the same probe failure: my apologies for calling it an unclean device shutdown, a previous responder mentioned that it might be caused by another OS not powering off the device cleanly. The attached is the error text. I was suggesting that "probe with driver iwlwifi failed with error -110" is not necessarily enough to go on. Am I wrong? Happy to help debug further / determine best steps to reproduce.

Hi, do you know when this happens? What happened before? You booted Linux after Windows or something like that?
