Loading a singleplayer world from the Monifactory Minecraft modpack seems to hang my system - the screen freezes and the system is only responsive to the crash and reboot sysrq commands.
I've tested this with a few kernels via the downgrade command. 6.16.7.arch1-1 is the last working kernel - 6.16.8.arch1-1 and 6.16.8.arch3-1 exhibit the issue.
Hardware is an AMD Ryzen 7 5700G CPU and AMD Radeon RX 7800 XT GPU. Software is KDE PLasma 6.4.5 on Wayland, though I'll try with some other desktop environments to see if that changes anything.
glxgears, vkcube, and vkmark all work, as well as vanilla Minecraft, so it's not just 3D in general causing the issue. Oddly enough, after rebooting and logging in after causing the hang, I get a black screen until I use Ctrl+Alt+F3 then Ctrl+Alt+F2 to change consoles.
This is the panic info I get from scanning the QR Code of the sysrq crash: https://panic.archlinux.org/panic_repor … 9644876032
Systemd Journal of the boot where this happens: http://0x0.st/KmdY.txt
There's messages about a lockup at the bottom - not sure if that's from this issue or just from the sysrq crash command.
Can anyone help identify what's causing the hanging? I can provide more info if needed.

Getting the same thing, seems like it's related to this. I got the same error described in the issue when I tried to load up a Minecraft world.

Happens with COSMIC DE as well. I'll try an X11 based DE in a bit.
I bisected the linux kernel and found that b2de0c9ce8e542b5cb4cd3944620d9dd1ea1f0ac "perf: Fix the POLL_HUP delivery breakage" is the first commit where the game crashes. Perhaps I should report this to the LKML instead?
I'm not sure if the pageflip timeout bug is related; I don't see the pageflip timed out message anywhere.

Whoops, you're right. That was a different crash I had with my browser. Sorry about that. I can confirm though that 6.16.7 works whereas 6.16.8+ doesn't.

same sympthoms (different system, but matters not)
seemingly same commit cutoff, doesn't crash on pre-b2de0c9

Came here to ask/report on the same issue, glad i wasn't the only one dealing with this.

I'm experiencing similar issue some modpacks on 6.16.10-arch1-1 (when I try to load my world, my entire PC freezes. I checked my RAM usage, and there was 1G of free RAM remaining + plentiful of Swap space, so this is not an issue) but I'm using RTX 3060Ti and Intel i5-11400F, so I'm guessing it is a arch issue.
Hope there will be a solution to this soon.

I had a similar issue to this recently. Had been playing minecraft modpack MC Eternal 2 which is based on MC 1.20.1 I think. I was playing for weeks on the latest cachy-os kernel from the Chaotic-AUR. I use PrismLauncher to launch minecraft.
I had been playing with impunity for weeks. Then all of a sudden (after a recent sudo pacman -Syu) the game started to crash.
Another interesting facet is I run a server on my own local machine (a terminal application) and the SERVER even crashed on load.
I was at my wits end trying to figure out what it was. I was checking the server log, systemd logs dmesg and all I could figure out.
I changed kernel to normal Arch kernel and the problem persisted.
Only way I've been able to resolve the issue is Reverting to LTS kernel (core/linux-lts 6.12.50-1) that works fine!
I will say this though. All the mods 10 which runs on a higher version of Minecraft and consequently a higher Java version I think 21 or something... worked fine... So perhaps it's an interaction between the JVM version and the kernel version? I'm not expert enough really to say that with any degree of certainty. I thought I'd just come in here with my take on the issue to see if it helped anyone in resolving theirs.
Also I'm Nvida if that helps.

having a similar issue, running with a Ryzen 7 4800H with an RTX 2060.
haven't played modpacks for a while but started experiencing system freezes on world load.
the issue seems specific to Java 17, or at least modded Minecraft works on higher java versions from what I've seen.
ram usage also didn't seem to be the problem, I have 16GB and allocated 5GB to Minecraft.
tried downgrading the kernel but it didn't mesh well with the NVIDIA drivers I have installed currently. i might try downgrading those too and see how things go.

Confirming that it does indeed work on kernel 6.16.7
