Kernel: 6.1.15-desktop-1.mga8 x86_64 10-Core Intel Core i9-7900X NVIDIA GP102 [GeForce GTX 1080 Ti] No problems with installation or reboot but had to run `drakboot --boot` to access it. nvidia driver module rebuilt and virtualb driver. GL graphics OK. VirtualBox launches clients OK. NFS shares mounted. Falkon, Firefox and Thunderbird working. VLC video and bluetooth audio working out of the box. CC:

tarazed25 I don't know why this happens, but newer kernels seem slower and slower on my i7-12700 machine. I ran two benchmarks: - PixInsight with kernel 5.17.4, 5.18.15, 6.0.9 and 6.1.15. - PassMark Performance Test with kernel 5.18.15, 5.19.7, 6.0.9, 6.1.2 and 6.1.15. PixInsight ---------- Operating system ....... 5.17.4-desktop-2.mga8 CPU time ............... 00:15.12 Operating system ....... 5.18.15-desktop-1.mga8 CPU time ............... 00:15.14 Operating system ....... 6.0.9-desktop-1.mga8 CPU time ............... 00:15.63 Operating system ....... 6.1.15-desktop-1.mga8 CPU time ............... 00:16.26 The time to run the benchmark is constantly increasing from kernel 5.17 to 6.1 (+7.5%). PassMark -------- kernel 5.18.15 Sorting: 48210 Thousand Strings/s Encryption: 24605 MB/s kernel 5.19.7 Sorting: 49549 Thousand Strings/s Encryption: 25085 MB/s kernel 6.0.9 Sorting: 52190 Thousand Strings/s Encryption: 24457 MB/s kernel 6.1.2 Sorting: 43657 Thousand Strings/s Encryption: 22174 MB/s kernel 6.1.15 Sorting: 43374 Thousand Strings/s Encryption: 22175 MB/s The other tests in PassMark remain pretty constant across the versions of the kernel I tested. Here, we see a significant decrease for kernel 6.1 for both sorting (-17%) and encryption (-10%). Is that due to some new security mitigation built into kernel 6.1? Passing mitigations=off to the kernel didn't help, despite lscpu saying that my machine is now vulnerable to Spectre v1 and v2. The benchmarks didn't change.

Is that due to some new security > mitigation built into kernel 6.1? Sorting and encryption should not need to touch the kernel much (or at all) so the reason is probably something else. Part of the CPU vulnerabilities mitigations are handled by microcode updates so that may be the cause for the slowdown you are seeing. MGA8-64 Plasma on AMD Phenom II 910, AMD HD 8490 graphics, Atheros-based wifi. This system also has the rtl8192eu, bbswitch, and broadcom-wl dkms packages installed, not because it has that hardware, but to see if they will build with the kernel under test. This is my last mga8-64 system for testing backported kernels - the rest have been converted to Cauldron testing. No installation issues to report with this kernel, and no issues noted after the reboot. CC:
