logs from debug kernel
Hi Takashi,
the tests with your debug kernel were a bit surprising.
In contrast to the unpatched kernel, the fan didn't start immediately after
loading the nouveau driver.
Even after logging into the Xserver it took a few minutes until the fan noise
started.
cat /sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/hwmon/hwmon0/pwm1
showed zero, until the fan noise started.
Then it showed: 100
That is quite different from the behaviour of the kernel with the reverted
patch.
That one constantly shows 20.
So, it seems that for any reason the debug kernel cause a sudden jump of the
fan speed from 0 to 100.
The attached debug log contain a dmesg and the journal log from before the fan
noise started and after.
