I been having issues with the cheap hp gaming laptop with Linux, One CPU core runs at 100% no matter that do i tried masking and disabling stuff, changing the Network card, adding Ram, and some desktops like Gnome forks had issues as well, KDE, and Mate work fine but it looks like it maybe has a Firmware, Driver or a Kernel issue, so far i tested it with Fedora, Fedora rawhide, Ubuntu and Mint, I’m going to test Debian next.
The laptop i had issues with Windows 11 works fine. https://www.walmart.com/ip/HP-Victus-15-6-inch-FHD-144Hz-Gaming-Laptop-AMD-Ryzen-5-8645HS-NVIDIA-GeForce-RTX-4050-8GB-DDR4-512GB-SSD-Mica-Silver-2024/5395277312
Edit Only Gnome 3 forks have issues with the Nvidia Drivers i will retest it at a later date with a new install and one CPU thread runs at 100% with all DE’s and OSes but Windows 11.
Edit 2 I think i found the issue AMD APUs on some systems with Nvidia GPUs will spam the system the bug report i found said to disable the iGPU. also Gnome forks work fine i think it was my fault for not disabling secure boot.
You’re describing a problem, but you’ll need to provide actual information. Is a process showing 100% util? Which process? What kernel version have you been testing on? Have you checked to ensure the amd-pstate module is loaded and getting frequencies properly?
A big issue i have it does not show any process running at 100% and i tested Kernel 6.8 to 6.11.Rc.x Nvidia Release, Beta etc I used performance and the default’s on Ubuntu and Fedora, i even tried to disable USB power saving mode that is a common issue with Linux on laptops, you think something like amd_pstate=guided etc will fix it? I seen many types of hardware, driver and firmware bugs over the years but i have not seen one like this in maybe 6-10 years and the last was a Intel atom CPU? and maybe a few Realtek Driver issue’s, i’m going to try Debian unstable etc soon, but i need to buy a USB SSD but my LMDE laptop with a backport Kernel works fine on my other laptop without a Nvidia GPU, and i think Debian’s Kernels has AMD-TEE support as of Kernel 6.9.7?, i have not had to debug hardware in a long time and i have a lot going on for the next few month’s so if up stream does not fix it i can start debugging I’m going to do a little bit like disabling hardware to see if it is the nic or a usb port etc.
You should almost always use
amd_pstate=guided/activeon anything newer than Zen 2, although Arch Wiki saysactiveis the default since kernel 6.5. Even if it doesn’t seem to fix the problem, it’s the preferred way to run those CPUs (if it works).guided+conservativescaling governor might help. Maybe it’s just a reporting bug tho, wouldn’t be a first for AMD.Form what i seen someone reported a bug that AMD APUs will spam a system with a Nvidia GPU.
If Gnome has issues but Plasma and Mate work fine, then it’s likely not firmware related, but rather a process in Gnome that’s using a core all the time. So find out what that process is, if it’s a common thing on Gnome and if it will finish if given enough time.
The CPU thread runs at 100% with all DE’s/OSes i tested so far and the Nvidia Drivers and Steam had bad issues with Gnome 3 forks, but work fine with Mate and KDE I even gave the Open Kernel Driver a ago before reinstalling a new OS with a a different DE.
topwould show you which process is actually using the cpu core.it does not is why i think it maybe firmware or Driver issues etc i will work on debugging it at a later date also it maybe jest bad hardware as well if not i’m not buying anything from HP.
Have you tried CoreCtrl? That has made life on my new Thinkpad much easier.
Can you confirm if there are processes sucking up all that cpu usage?
Also, if it’s only some desktops with that issue, then it’s clearly not a lower level issue but something to do with GNOME and derivatives
all DE’s have cpu usage issues and it does not show me whats going on. also i miss the part Nvidia issues was gnome 3 forks only.
Hard to know for sure without knowing what exactly it is you’re trying to run, but since you’re using an AMD processor, I would guess it’s NOT a firmware/driver issue. New Intel processors would be a different story.
Even today, not every application is programmed to use multiple cores effectively, or at all. Again, we need to know what application(s) you’re running when this happens
nothing running, nothing in top it just has one CPU thread at 100% also this laptop has a NPU and I think it is a Nvidia 4050 Max-Q.
More than distro hopping maybe try out a zen kernel or compiling kernel yourself and changing kernel config and scheduler, or a newer version of the stock kernel?
I’m not super current on what’s in each kernel but I’d expect latest mainline to handle newer processors better than some of the older stable kernels in some of the more mainstream slower releasing distros.
it maybe AMD-TEE issues or a Driver/Firmware bug i really don’t know at this point it looks like i may have a lot of debugging to do does Zen support AMD-TEE?
Maybe worth trying an alternative OS with a different kernel entirely from Linux, as a live USB. For example Haiku or ArcaOS?
However if you’ve tried Windows and not had the issue then it may not add anything as you nay already have excluded defective hardware?
