[SOLVED] fancontrol isn't working since Jan 2022

Hi all.
My little NAS is running Archlinux and rely on fancontrol to adjust my case fan.
After a reboot in Jan 2022, I found that fancontrol isn't working anymore. And I have some investgation.

Here's what I found:
1. /sys/class/hwmon/ is missing something casuing fancontrol refused to start.
2. it87 driver seems like have some problem.
here's my dmesg.

[    6.864043] it87: Found IT8772E chip at 0xa30, revision 1
[    6.864066] it87: Beeping is supported
[    6.864076] ACPI Warning: SystemIO range 0x0000000000000A35-0x0000000000000A36 conflicts with OpRegion 0x0000000000000A36-0x0000000000000A36 (\SIO1) (20210930/utaddress-204)
[    6.864084] ACPI Warning: SystemIO range 0x0000000000000A35-0x0000000000000A36 conflicts with OpRegion 0x0000000000000A35-0x0000000000000A35 (\SIO0) (20210930/utaddress-204)
[    6.864090] ACPI: OSL: Resource conflict; ACPI support missing from driver?

but lsmod didn't show it87 and I have checked kernel config

[root@hyw-tiny ~]# zcat /proc/config.gz |grep -i it87
CONFIG_GPIO_IT87=m
CONFIG_SENSORS_IT87=m
CONFIG_IT8712F_WDT=m
CONFIG_IT87_WDT=m

And then I tried to install it87-dkms-git and it doesn't help.

What may went wrong?

Update on Jan 23, 2022

I checked my pervious config (I have transferred from grub to systemd-boot, and that's time it doesn't work.), I found I missed acpi_enforce_resources=lax in kernel parameters. Adding it solves the problem.
So can anyone explain?
