acpi

Dear community, I have a Lenovo Laptop T470 which runs FreeBSD-13,2p3-RELEASE. The device has a row of function keys F1 to F12. With an additional simultaneous Fn key press they provide special functions as XF86AudioRaiseVolume, XF86MonBrightnessDown, XF86Favorites and more. The default FreeBSD...

Hi, I would like to use the AMC6821 I2C fan controller that came on my SolidRun HoneyComb LX2 (NXP LX2160) board, but it does load properly in FreeBSD (13.2-RELEASE). I can only see it with devinfo: What do you think could be needed to get it to work properly? Thank you!

I compiled acpi and am trying to boot with it in order to fix some weird kernel spam in the console. acpi_tz0: _CRT value is absurd, ignored (256.1C) I constantly get this type of message and overwrite the output in the tty. My laptop tolerates this: HP Compaq nx6320 I read this...

I have recently upgraded to FreeBSD-13.0 with KDE Plasma from 12.2. Before, in Gnome shutting down button worked as it is intended to be. But, after the upgrade pressing shutdown button or shutdown -p now --> system shuts down; 3-4 seconds later restarts. This is a persistent behaviour after...

Hi, How could I try and debug, and hopefully fix, the ACPI tables dumped by acpidump? If I run acpidump -t, I get: ... Type=INT Override BUS=0 IRQ=9 INTR=9 Flags={Polarity=active-lo, Trigger=level} */ acpidump: RSDT entry 21 (sig SSDT) is corrupt /*...

Hello to everyone. It's again me. I'm trying to understand what are the statement that I should put into the right configuration files to disable totally the acpi,since it seems that it is needed to boot the cdrom with freebsd with qemu and kvm. (for more informations about this,give a look at...

I did some testing and executed a "# poweroff" on the host system. Judging on the speed that the machine shutdown, I don't think the bhyve VMs went through a graceful shutdown. Is there any way to tell bhyve VMs to gracefully shutdown? (I think other virtualizers such as VirtualBox has...

Not sure this is the correct forum to ask this question, but i'm having a heck of time figuring out how to remove the suspend options in the leave menu of kde5 plasma. I'm finding a lot of varying information about polkit stuff which i haven't worked with before, but everything I've tried...

Hi, My laptop is a dell latitude 7240 with a Haswell cpu. Mate Desktop is installed. My goal is to get the “fn” working to change the screen brightness. I installed https://www.freshports.org/graphics/intel-backlight and I can change the screen brightness by entering ,for.e.g...

I've been using FreeBSD for a decade on servers and infrastructure. Last weekend I thought it's time to give it a chance as a desktop OS. For this, I've been installing FreeBSD 12.1 on my old Lenovo Thinkpad X1 Carbon (3rd gen). I managed to install the base system, get wifi to work, have i3...

Hi all, I know this is a tricky one to solve but I'd be interested to know how I can debug this further, or at a minimum, just stop the machine from suspending on it's own as it's impossible to recover from it once it happens without a power cycle. Disablig ACPI completly with a boot hint...

I fixed an ACPI problem with an old motherboard. Here, I document the steps I used to repair it: Trying FreeBSD 12.0 on an old Pentium 4 machine, with Intel D915GAV motherboard, latest BIOS version. Everything seems to be working OK except that I have an ACPI error report in dmesg on boot...

Hello, I'm new to FreeBSD and I tried to install it on my Acer Aspire E17 laptop, but I could not start the installation process, due to the following error : acpi_ec0: EcCommand: no response to 0x84 The message is displayed on a new line every second, which gives the following screen : I...

Sorry, not sure if i can put a question here but all this info https://www.freebsd.org/projects/acpi/ looks very outdated. Any idea about where to ask? Regards. W.

I was wondering what would be a possible reason to get the message unknown oid 'hw.acpi.thermal' as response to sysctl hw.acpi.thermal... I'm running FreeBSD 12 on a Xeon rig and ACPI running, so I expect to see also the thermals. But this is not the case. The thermals seem to be missing. What...

Hi Forum, When I boot up FreeBSD for the first time (not completely the first time - as I've had earlier versions installed and had the same problem, but didn't report it because I was trying to find a solution.) the root password or the user password just says login incorrect. I am sure the...

Recently I decided to run exclusively FreeBSD 11.2 (RC3) on my new Thinkpad T480. I'm using drm-kmod-next, overall the system runs quite well. But one really annoying problem is that none of the FN-brightness up/down, wireless, etc.. was working. Even using the acpi_ibm driver. It took me a...

If I take out the laptop battery, do I confuse the acpi system? I get kernel spam containing: No handler for Region [RCM0] acpi_ec0: evaluation of query method _Q42 failed: AE_NOT_EXIST Is it due to me removing the battery, and if so, how can I tell acpi system not to look for it?

Hi, I got a new Dell Precision 5510 and I was planning to install FreeBSD 11 on it. After inserting my FreeBSD 11.1 AMD64 Release DVD, during boot and after boot finished, my system keeps showing this message: ACPI Error: Method parse/execution failed [\_TZ.TZ00._TMP] (Node...
