This affects me as well, same exact symptoms, but I'm in the same boat at Lorenzo 4 comments above.
Pardon my inexperience in kernel module building, but if this is relevant with my Fedora 36 install, I would be willing to build and test this, however I would need a pointer at a wiki/docs on where to obtain source and how to activate.

[Fix] Full t7xx driver is still under development and some of them have already accepted and merged in mainline kernel. The following commits are once in the mainline and are reverted in v6.0: d20ef656f994 net: wwan: t7xx: Add AP CLDMA 007f26f0d68e net: wwan: t7xx: Infrastructure for early port configuration 140424d90165 net: wwan: t7xx: PCIe reset rescan 87dae9e70bf7 net: wwan: t7xx: Enable devlink based fw flashing and coredump collection The first patch implemented the other AP-CLDMA, and with that applied, platforms in question may suspend and resume normally as every bits are in position. However, while these patches had been reverted for another revision that is still being worked on by the hardware vendor, a minimum, sauced patch is created to work-around this first to meet project schedules, and will be reverted and superseded with a final, mainline landing revision. [Test Case] Trigger suspend and there should be no more suspend errors from t7xx: mtk_t7xx 0000:58:00.0: [PM] SAP suspend error: -110 mtk_t7xx 0000:58:00.0: PM: pci_pm_suspend(): t7xx_pci_pm_suspend+0x0/0x20 [mtk_t7xx] returns -110 mtk_t7xx 0000:58:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1a0 returns -110 mtk_t7xx 0000:58:00.0: PM: failed to suspend async: error -110 [Where problems could occur] The t7xx driver is still incomplete and we're staging aforementioned 4 patches in internal experimental kernels for development use. [Other Info] This affects Kinetic and above, so only Unstable, Kinetic and OEM-6.0 are nominated for fix. ========== original bug report ========== 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 0000:58:00.0: [PM] SAP suspend error: -110 mtk_t7xx 0000:58:00.0: PM: pci_pm_suspend(): t7xx_pci_pm_suspend+0x0/0x20 [mtk_t7xx] returns -110 mtk_t7xx 0000:58:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1a0 returns -110 mtk_t7xx 0000:58:00.0: 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.
