Title: Suspend issue with AMD Ryzen 8840U CPU and kernel 6.8.0-45-generic Status in linux package in Ubuntu: New Bug description: I am running a new installation of Ubuntu noble 24.04 x86_64 (kernel 6.8.0-45-generic) on a brand new Thinkpad T14 Gen 5 (AMD Ryzen 7 PRO 8840U w/ Radeon 780M Graphics (16) @ 6.08 GHz) The machine does not suspend properly, which I noticed after returning from work with it in my backpack, taking it out and it was hot. While suspended the screen is in fact off, and the relevant LEDs enter a "breath" mode, indicating a suspended state, but there is an audible mechanical "tick" sound coming from the bottom, where I suppose the fan is located, and the laptop produces heat (gets hot if it's in a closed environment like my backpack) At first I thought it was a "lid closed" issue, but after further experimentation turns out that it's not a lid issue, but rather a suspension issue; suspending from the power button has the same result I could not reproduce this behaviour on Windows (I am dual booting, Windows Fastboot is off btw); suspending works properly; tested it, no "tick" sound, no heat. P.S. for what it's worth, my Thinkpad x13 Gen 1 on ubuntu 22, same kernel version on AMD Ryzen Pro 7 4750U, has no issues with suspend. Attaching system specs below. Please let me know what other info I need to provide Thanks.
