[Kernel-packages] [Bug 1990700] Re: Fibocom WWAN FM350-GL suspend error (notebook not suspend)
This bug is awaiting verification that the linux-ibm/5.19.0-1015.16 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-kinetic' to 'verification-done-kinetic'. If the problem still exists, change the tag 'verification-needed-kinetic' to 'verification-failed-kinetic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Kernel-packages] [Bug 1990700] Re: Fibocom WWAN FM350-GL suspend error (notebook not suspend)
Hi Vicamo, We had a detailed discussion on this. We would suggest to use the patch with below commit id d20ef656f994 net: wwan: t7xx: Add AP CLDMA instead of the earlier shared workaround for resolution of the suspend issue. This patch can be integrated without dependency with any other patch and this would fix the suspend resume issue. Please do not take the other three patches. This patch would not cause any other side effect.

[Kernel-packages] [Bug 1990700] Re: Fibocom WWAN FM350-GL suspend error (notebook not suspend)
Just a FYI: I reported this bug as well, concerning a closely related Fibocom modem on an Asus Expertbook laptop to Fedora at https://bugzilla.redhat.com/show_bug.cgi?id=2131366 I have not as yet been able to try the patch because I've never built a kernel on Fedora and currently I'm stuck. In other words I'm an idiot. I'll let you know if I figure it out, but meanwhile I thought it just might be useful to know there is another bug report on this. ** Bug watch added: Red Hat Bugzilla #2131366 https://bugzilla.redhat.com/show_bug.cgi?id=2131366 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1990700 Title: Fibocom WWAN FM350-GL suspend error (notebook not suspend) Status in HWE Next: New Status in linux package in Ubuntu: Incomplete Bug description: Hi, I found a "little" problem with Fibocom WWAN FM350-GL 5G modem in module mtk_t7xx .

It was reported internally that following patch series fixed this issue:
87dae9e70bf7 net: wwan: t7xx: Enable devlink based fw flashing and coredump
collection
140424d90165 net: wwan: t7xx: PCIe reset rescan

d20ef656f994 net: wwan: t7xx: Add AP CLDMA
However, they were then reverted in netdev-next in commit bf294c3feafe
("Revert "Merge branch 'wwan-t7xx-fw-flashing-and-coredump-support'""),
so we're still waiting for the updates from chip vendor.

Expected state: sleep occurs when the device is put to sleep -
including the modem. When you wake up, you will wake up, including
activating the modem and logging into the operator's network.

[Kernel-packages] [Bug 1990700] Re: Fibocom WWAN FM350-GL suspend error (notebook not suspend)
apport information ** Tags added: apport-collected focal ** Description changed: Hi, I found a "little" problem with Fibocom WWAN FM350-GL 5G modem in module mtk_t7xx . Power management for this modem is bad. When the notebook goes to sleep/suspend, kernel module mtk_t7xx return an error: mtk_t7xx :58:00.0: [PM] SAP suspend error: -110 mtk_t7xx :58:00.0: PM: pci_pm_suspend(): t7xx_pci_pm_suspend+0x0/0x20 [mtk_t7xx] returns -110 mtk_t7xx :58:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1a0 returns -110 mtk_t7xx :58:00.0: PM: failed to suspend async: error -110 So power management failed to suspend: PM: Some devices failed to suspend, or early wake event detected And the notebook not suspend and wake up again. It must be this module, because if I remove the module first (modprobe -r), the laptop goes to sleep and wakes up normally. However, after reinserting the module, the modem no longer appears in the system. Expected state: sleep occurs when the device is put to sleep - including the modem. When you wake up, you will wake up, including activating the modem and logging into the operator's network.
