Linux 5.15.0-116 or greater breaks xmrig

[Anant]

I am suddenly getting hashrates between 0.63 to 0.74 H/s where I would get 640 to 730 H/s earlier (1000x slower). Initially, it would go away after a few reboots but now it won't.

I stumbled upon the problem when using Linux Mint, but it hinges on the kernels, which Ubuntu ships.

I initially encountered it when using linux 5.15.0-116-generic & 5.15.0-117-generic on Mint 21.3. It also occurs when using kernel 6.8.0-39-generic, when using Mint 22.

5.15.0-113 was the kernel available immediately preceding 5.15.0-116 in Mint 21.3, and there were no problems when using this kernel.

My CPU is an i3-6006U, unsure if that matters.

XMRig version latest: https://github.com/xmrig/xmrig/releases/download/v6.21.3/xmrig-6.21.3-linux-static-x64.tar.gz

Discussed on the Linux Mint forums, is a bug in the kernel ubuntu ships: https://forums.linuxmint.com/viewtopic.php?p=2501154&sid=d324ed8ce5b30d882e3b5ac217436968#p2501154

Hi, @Anant.

Thank you for your report. Could you please run the following command to help us collecting the information of your system?

apport-collect 2074520

Thanks.

@rickywu : I have reinstalled Mint 21.3 (equivalent of Jammy) and am using kernel 5.15.0-113 because I needed xmrig. Hence, I cannot send this report for Mint 22 (kernel 6.8.0-39, equivalent to Noble), as that install was erased.

Which kernel would you like me to boot in Mint 21.3 before running apport-collect?

Hi @Anant,

Could you please run the apport-collect on your 5.15.0-116 kernel? We need the information of your system when the problem occurred.

Thanks.

@Anant and @rickywu,

The current build of Mint 22 (as of 15 Dec. 2024 seems to execute xmrig-6.22.2 without a problem.
