acpi

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...

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...

Acpi_toshiba is loaded, but does not work on Toshiba A300 notebook. How to fix that? [egor@h ~]$ kldstat Id Refs Address Size Name ... 8 1 0xffffffff82322000 53b0 acpi_toshiba.ko ... [egor@h ~]$ sysctl -a|grep tosh [egor@h ~]$

I experimented: $ grep -i acpi /boot/loader.conf hw.acpi.power_button_state="S3" $ Not effective. I guess, because hw.acpi.power_button_state is a sysctl variable but not a loader tunable; acpi. Is there a way to have the button suspend by default? TIA

Hi all, I'm trying to install FreeBSD 11 Release on one of my machines and I noticed that dmesg shows these warnings: ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Pm1aEventBlock: 64/32 (20160527/tbfadt-650) ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Gpe0Block: 64/32...

I installed the standard FreeBSD 11 on a Dell Latitude 7480 laptop, and got the same problem of https://forums.freebsd.org/threads/59627/ . sysctl -a hangs after the line hw.acpi.battery.units: 1 Unfortunately on this latest business laptop, disabling ACPI is NOT an option, as confirmed by Dell...

Dear Forumers, I have been battling all day with a problem I can find very little information about and I was hoping you could give me a hand. I'm putting this issues in this forum only because I only did a fresh new install today and have been trying to resolve the issue basically the better...

I'm trying to install FreeBSD 10.3 (amd64) from a CD on Thunder h2000M (S3992) (it is an old motherboard) but it hangs at this line. kbd1 at kbdmux0 acpi0: (110508 RSDT1625) on motherboard acpi0: Power Button (fixed) acpi0: Sleep Button (fixed) cpu0: (ACPI CPU) on acpi0 cpul: (ACPI CPU) on...

Hi, I recently added a zfs disk array to my old HP 585 G1 Server. Immediately there was kernel panics and I have spent quite a bit of time figuring out what was really wrong. The system has 4 cpu cards with opteron double core processors. Each card has 4x2 gigabyte memory 4x2x4 = 32 gigabyte...

For some reason I'm trying to get FreeBSD installed on a notebook (weird, I know) and I'm having trouble getting sleep mode working right. If you run acpiconf -s 3 (or even quit X with Ctrl-Alt-Backspace) while X is running, the screen does this, and if you run it from the command line...

Hi all, I'm using a Samsung NP530U3C notebook (Core i3 3217U, HD Graphics 4000) with 10.2-RELEASE/GENERIC. Display brightness can't be adjusted via fn keys, but via terminal i.e. intel_backlight <value> works sysctl hw.acpi.video.lcd0.brightness=<value> also works I want to control it via the...

In May I started with 10.0-RELEASE on an ASrock E3C224D4I-14S. The system had low power consumption and powerd did a good job lowering the CPU frequency. However starting from 10.1 (and now 10.2-RELEASE) I keep getting high CPU consumption due to a process called {acpi task}. BIOS upgrades or...

Hello, I'm trying to lock my notebook whenever the screen lid is closed. I tried to combine /usr/bin/lock -vpn with ACPI control, by adding the lock command to /etc/rc.resume. ACPI sleep/resume is working fine, but when the notebook is resumed, lock is not executed, and I'm back at the shell...

Hi y'all! First post here so thanks a lot for caring enough to read. I chose PCBSD because I wanted to start using FreeBSD for my personal computer ASAP and did not have the time to set everything up myself. On my Samsung NP550P7C I'm running: FreeBSD zeno 10.1-RELEASE-p26 FreeBSD...
