From fd6e7c8949218df6b61a5b9186aba3f9d1d91f75 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 9 May 2022 20:16:26 -0500 Subject: [PATCH] Set autosuspend delay for Fibocom LG850-GL It has been shown that the autosuspend delay for this device enacted by modem manager will race with suspend and cause system suspend failures. This occurred in ChromiumOS on a chromebook, but there is no reason it won't happen in regular notebooks with the same WWAN. To avoid the failure delay autosuspend to a frequency longer than the polling rate used by modem manager.
