虚拟-0温度是错误的。

Question

当我运行sensors时，它返回以下内容：

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +51.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +50.0°C  (high = +100.0°C, crit = +100.0°C)

acpitz-virtual-0
Adapter: Virtual device
temp1:        +48.0°C  (crit = +200.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM

acpitz-virtual-0温度总是在48度，风扇也不会因此而开始运转。

sensors-detect提供以下输出：

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): Module cpuid loaded successfully.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): Found unknown SMBus adapter 8086:9c22 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Next adapter: i915 gmbus ssc (i2c-0)

Do you want to scan it? (yes/NO/selectively): 

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 
Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.

Unloading cpuid... OK

systemctl status fancontrol.service输出：

● fancontrol.service - fan speed regulator

而lsmod | grep acpi给出

我有Ubuntu 18.4。有办法解决这个问题吗？

Answer 1

我通过降级到内核的旧版本来解决这个问题。不完全是我喜欢的解决方案。希望它能在Ubuntu18.10内核的下一个版本之前得到修复。
