Quoting from it: > I noticed a few days ago, after Fedora moved to Kernel 6.5, that my Intel LTE Modem was not working anymore after resuming from standby. > > The journal listed this error message multiple times: > kernel: iosm 0000:01:00.0: msg timeout > > It took me a while to determine the root cause of the problem, since the modem did not work either in the following warm reboots. > Only a shutdown revived the modem. > > I did a bisection of the error and I was able to find the culprit: > > [e4f5073d53be6cec0c654fac98372047efb66947] net: wwan: iosm: enable runtime pm support for 7560 See Bugzilla for the full thread. Anyway, I'm adding this regression to regzbot: #regzbot introduced: e4f5073d53be6c https://bugzilla.kernel.org/show_bug.cgi?id=217996 #regzbot title: pm support for Intel 7560 makes the modem stops working after resume Thanks.
