plumis, thank you for your bug report. Recent Linux kernels and thus recent Fedora versions work fine with s2idle. The S3 support in the BIOS is really only for RHEL where the kernel does not fully support s2idle yet. Since Windows 10 uses s2idle the s2idle BIOS code tends to be much better tested; and battery usage while suspend should be just as good (or better) with s2idle mode as with S3. So I always advice people to use s2idle mode when running Fedora. Inline with this my advice to you for this problem is to simply switch back to / leave the setting at s2idle. I've added Mark Pearson from Lenovo to the Cc. Mark, can you please take a look at this issue ? Hi, Thanks for your reply. I know that s2idle could be a better choice. but my thinkpad with LTE module and have issue with s2idle suspend. It stop working after wake up from s2idle. Just like touchpad with S3 Deep suspend I reported in this issue. https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/372#note_919309 And surprisingly LTE wake up issue is gone under S3 deep suspend. This make me in a dilemma: s2idle or S3, LTE module or touchpad. It will be great to see you Cc this issue to Lenovo. I'm not sure LTE issue is Kernel related or Modemmanager related. So should I have to report a new bug about LTE wake up issue? > So should I have to report a new bug about LTE wake up issue?
Normally we try to have one bug per issue, but first lets wait to see what Mark has to say, maybe there already is an open bug for this.
Hi, We test and certify with S0ix on this platform as S3 isn't supported on Tigerlake processors; S0ix is recommended and getting support for S3 is going to be hard. I'm slightly curious as to why they added the S3 support option in the latest BIOS - I hadn't realised that was happening. I assume you have the Quectel LTE module? We're still working on enabling that so it's cool you have that working at all. Have you picked up all the patches that are upstream? support for it was only included recently. (I'm also intrigued how you got around the FCC lock as we haven't released the utility for that either) My recommendation here would be a new bug marking it as specifically LTE related. If you could raise that, and tag me on it, I can follow up with the driver team and Quectel for status. It will come with the caveat that we're still working on it, but the driver is upstream and it's under testing so it should work. Once our test team have finished I'm hoping I can get semi-official instructions out on how to enable WWAN. Mark Hi, thanks for your reply and explansation. I'll stay with s2idle option. My X1C 9th is Chinese Version, Yes it has Quectel em05-ce wwan module with a LTE simcard preinstalled (5GB/month plan). I don't know about FCC lock. I just install Fedora on my laptop and try to enabled LTE with network manager. And I found ……It works, but stop working after resume from suspend. As you said Quectel em05-ce is still work in progress, I'll make a new bug report about this issue. Thanks for your help. Mark. I made a new bug report about LTE https://bugzilla.redhat.com/show_bug.cgi?id=1966283 I don't know how to make it LTE related so it's in Kernel selection. Thanks - I've commented on the other bug and raised an internal ticket at Lenovo for tracking. Hans - I assume we can close this one in the mean time? Mark (In reply to Mark Pearson from comment #7) > Hans - I assume we can close this one in the mean time? Ack, closing. |
