I've tested Linus git tree from right now + hwmon-next and I cannot
make it crash.
The driver seems to work fine here and temperature reportings are very accurate
on all HDDs on that box. ( 8 x Seagate IronWolf 2 TB (ST2000VN004) )
What I've noticed however is the nvme temperature low/high values on
the Sensors X are strange here.
I'm not sure it is a v5.5 issue or a hwmon-next one right now, I
didn't boot a vanilla v5.5-rc5 yet.
Both nvme's are Samsung SSD 960 EVO 250GB.
They look like this:
nvme-pci-1300
Adapter: PCI adapter
Composite: +27.9°C (low = -273.1°C, high = +76.8°C)
(crit = +78.8°C)
Sensor 1: +27.9°C (low = -273.1°C, high = +65261.8°C)
Sensor 2: +29.9°C (low = -273.1°C, high = +65261.8°C)
nvme-pci-6100
Adapter: PCI adapter
Composite: +23.9°C (low = -273.1°C, high = +76.8°C)
(crit = +78.8°C)
Sensor 1: +23.9°C (low = -273.1°C, high = +65261.8°C)
Sensor 2: +25.9°C (low = -273.1°C, high = +65261.8°C)
