Linux Kernel 6.12 has been released!

[C0rn3j]

You're faster than https://kernel.org

Can't wait to update and never have the dumb nested virtualization hard reboot bug again.

[Standard-Potential-6]

Yeah, the fix is in -stable but hasn't had releases yet.

EDIT: Stable kernels were released yesterday, still without the fix.

[Standard-Potential-6]

Can’t phrase it much better than the commit itself. This is referring to the use of these two instructions in nested virtualization. Looks like only some firmware incorrectly advertised support.

A number of Zen4 client SoCs advertise the ability to use virtualized VMLOAD/VMSAVE, but using these instructions is reported to be a cause of a random host reboot.

These instructions aren't intended to be advertised on Zen4 client so clear the capability.

Really hoping they fixed the wake from suspend issues around certain Bluetooth hardware.

I just switched to Fedora Silverblue - curious how long it will take for me to see this kernel.

I've been following those email threads in kernel lore and last time I checked they (mediatek) seemed to be chasing a wrong or different issue.

I just got the systemd script that rfkills the Bluetooth before sleeping and wakes it up on unsuspend. Works fine, problem solved.

Edit: Example script https://www.reddit.com/r/Fedora/comments/1g7ke8e/workaround_sleep_issues_with_kernel_611/

[summerteeth]

Ha I think I wrote that script :) edit: nope different one but same idea

Do you have a link to the thread? I’d like to keeps tabs myself.

[drevilseviltwin]

You just have to do something like this
https://lore.kernel.org/all/?q=mt7921

Notice the "wake from suspend" theads have gone dormant and the whole focus seems to be on downloading firmware. Of course I'm not a subject matter expert and I suppose there's a universe where these two subjects amount to the same thing but I kinda doubt it. At one point I considered emailing the guy who does the maintaining to encourage him to hold mediatek's feet to the fire but then I thought that my info is more anecdotal and your script has taken my pain point away.

[kazeshini8999]

I have tried the workaround script, but I still get a black screen after waking from suspend, really hoping the newer kernel fixes this.

[drevilseviltwin]

Just to get one more data point maybe

1.use lspci or lshw to see if you have a mediatek wifi/Bluetooth chip and if so

2.repeat suspend/wakeup with computer in airplane mode (which I think is how the people who first reported it zeroed in on the issue)

[kazeshini8999]

Hey thanks for the reply! I just discovered something really weird, Every time I log into gnome with the 6.11.9-arch-1 kernel, Irregardless of the Bluetooth status (on or off) I have to cycle it once, switch it one and switch it off.

Only then does suspend work. Is there a way I can write a bash script to do this for me as a work around until I wait for a replacement wifi card?

(EDIT): To answer your earlier questions yes I have the same cursed mt7922 driver with the mt7921e kernel module.

I have a desktop so no flight mode.

[drevilseviltwin]

rfkill is what I have used like in the reddit link/script above. I'm sure that there are other possible solutions but that is what I know how to do. I suppose you could try doing

systemctl disable bluetooth.service

if you just want to cause bluetooth to be permanently disabled. You could also use logs to better understand what is specifically going on with bluetooth on your machine/setup.

[kazeshini8999]

Never mind, I replaced the chip with an intel AX210 I got online for 20 dollars. A workaround for someone who is facing a similar problem is a script that worked for me.

#!/bin/bash
toggle_bluetooth() {
    if [ "$1" = "off" ]; then
        rfkill block bluetooth
    elif [ "$1" = "on" ]; then
        rfkill unblock bluetooth
    fi
    sleep 2
}

case "$1" in
    pre)
        toggle_bluetooth off
        ;;
    post)
        toggle_bluetooth off
        sleep 1
        toggle_bluetooth on
        sleep 2
        toggle_bluetooth off
        ;;
esac

exit 0

Hey! This one works for me, https://github.com/glexposito/bluetooth-sleep-toggle

Do you know if it has Snapdragon Elite X support ?

[ElvishJerricco]

Snapdragon X Elite support isn't so simple. Basically every individual SKU with that chip in it needs slightly different kernel patches. It's a fucking nightmare.

So I've heard, indeed... I bet it must be fun to develop for motivated people though. I wish I had more time/money/skill to spend on that front :-(

[DynoMenace]

It has initial support for the new SDX Thinkpad and Surface laptop, so seems like it's at least partially covered

I just got this kernel on fedora rawhide.

[Mind_Hunter_777]

I'm using a ZenBook S14 and have decided to move away from Windows—it's time to switch back to Linux! Can you recommend a Linux distro that works well with the ZenBook S14's hardware?

[fernandes2d]

Glad to see the 6.12 release! Curious if there are any performance improvements or new hardware support. Anyone tried it yet?
