Title:
[ThinkPad X1 Carbon 20BT] Fails to suspend from the second time
Status in linux package in Ubuntu:
Expired
Bug description:
version: 3rd(2015 version) on Trusty(14.04)
It suspends and resumes successfully at the first time, then WWAN
devices disappear and fails to suspend.
workaround 0:
BIOS, Always On USB to disable, USB 3.0 mode to enable
workaround 1:
disable cdc* modules in rootfs and initramfs(you will lose WWAN feature)
workaround 2:
reset that WWAN device from xHCI(USB 3.0) port to EHCI(USB 2.0)
We still need a fix.
