which platform is this?

[jeremyszu (os369510)]

@Jun,

It's EliteBook 850 G8

HP ZBook Fury 17.3 Inch G8 Mobile Workstation PC face this issue as well

[Rex Tsai (chihchun)]

The modem based on Intel XMM7360 can support both PCI and USB mode, the HP's UEFI does not support switching the model to USB mode.

The WWAN suspend D state is D2 instead of D3, under windows. The WWAN under PCI will block suspend-to-idle on Linux.

Canonical CE team planned not to fix this issue. A workaround has been proposed https://lkml.org/lkml/2021/3/24/489

[Václav Bohata (vaclav-z)]

There is already a solution: https://github.com/xmm7360/xmm7360-pci
Ubuntu should include it to be more friendly

[Kai-Heng Feng (kaihengfeng)]

7360 is supported now:
$ modinfo iosm | grep 7360
alias: pci:v00008086d00007360sv*sd*bc*sc*i*
