Subject: fasolo: blacklist acpi power meter. rt#6974
X-Git-Url: https://git.adam-barratt.org.uk/?a=commitdiff_plain;h=45d92970445c4030718101dfedbdf72be7017e81;p=mirror%2Fdsa-puppet.git

fasolo: blacklist acpi power meter. rt#6974

fasolo dmesg is full of:
```
[3723410.864219] ACPI Error: SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32 (20160831/exfield-427)
[3723410.890212] ACPI Error: Method parse/execution failed [\_SB.PMI0._PMM] (Node ffffa0e2fe877280), AE_AML_BUFFER_LIMIT (20160831/psparse-543)
[3723410.920171] ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM (20160831/power_meter-338)
```

I believe a fix/workaround might be blacklisting acpi_power_meter kernel module which does not seem to work due to BIOS bug in those machines.

`echo "blacklist acpi_power_meter" >> /etc/modprobe.d/hwmon.conf`
