Tested Kernels BMQ and PDS - freezing pc while cut / paste #49

Closed wolfyrion closed 1 year ago

wolfyrion commented 1 year ago

I have found a very weird bug...

I have cut and paste around 200 files (a variety of very small and large files ) from dolphin to synology nas (mounted )

The result was freezing the PC

I have test this with Cachy BMQ and PDS kernel both having the same issue

I have tested this with TKG BMQ and PDS everything is working fine.

I have tested this also with LTS and Arch default kernel everything is working fine

I have tested again the CachyOS kernels and the PC is still freezing while cut/paste from dolphin to NAS

Could you test another kernels like bore or tt and let us know if that bug still occurs?

Hey @wolfyrion,

PRJC has actually some known issue. It got some days ago synced from Alfred, the patch creator. I don't know if the known bugs (e.G freezing) are solved with the update from alfred. I have updated the patchset (https://github.com/CachyOS/kernel-patches/commit/94f5d8cb1afa5fc27f14c383b8e310c4b61d6ec2) here.

Maybe give it a try as soon the kernels are compiling into the repo. Also it would be good if you test another scheduler (CFS, BORE, TT), if the issue is there still present.

Regards

With any PDS or BMQ or LQX Kernel somehow I get around 40-50 more FPS in some games. (I have an old threadripper 1950x and a radeon 6900)

I have tried BORE but I didnt see any significant performance gain. For example in shadow of Mordor benchmark with any PDS or BMQ or LQX kernel I get max FPS around 384 but with bore and other kernels like Xanmod I get around 346...

I dont have time to test bore but surely I will test the PDS kernel 6.0.12 when is ready and report back

We meant for you to check if copy/paste errors also occur on other schedulers. This would make it very easy to track down the culprit of such hangs.

I think it is related to this: https://bugs.archlinux.org/task/76736?project=1&order=lastedit&sort=desc

Actually im wondering about that you have 50 FPS more when using PDS or BMQ (LQX is using PDS). I can't reproduce such results with my 5900X. Also there are other benchmarks out there, which is showing that PDS/BMQ is equal to CFS based schedulers(bore) which covers also my results.

Please check the above link, if you are hitting equal issues and if it is solved with 6.0.12. I have tested now for some hours PDS with 6.0.12 and I had no locks on my side. But I was not able to reproduce it with 6.0.11.

Also if you would provide some logs with journalctl or anything it would help.

It seems with Linux-cachyos-PDS 6.1.0-1 I dont have this issue...

Upgrading to 6.1.0-2 -> Main pc with Threadripper doesnt boot at all - freezing at initializing Ram However the other intel pc is booting just fine....

sirlucjan commented 1 year ago

PRJC from 6.1.0-2 included official upstream version and it's broken. We have added 6.1.0-3 with previous PRJC version

The rebuild should be done soon with the old version

@wolfyrion If you think the problem is solved then I would ask you to close the thread.
