[[BUG]Latest kernel update makes Odroid unuseable]

I always check the forums before I push a kernel update but luckily came out of this upgrade unscathed

 

However from this thread I noticed that my uImage is also mismatched (odroid HC4)

$ uname -a
Linux odroid 6.4.13-edge-meson64 #4 SMP PREEMPT Wed Aug 30 12:52:45 UTC 2023 aarch64 GNU/Linux

$ strings /boot/uImage | grep "Linux version"
Linux version 6.2.0-rc3-meson64 (root@ecf00258e87e) (aarch64-linux-gnu-gcc (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 8.3.0, GNU ld (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 2.32.0.20190321) #23.02.2 SMP PREEMPT Fri Feb 17 23:06:22 UTC 2023

 

@jbergler where did you find the mkimage flag settings for that command? I want to be sure it'll be the same for the HC4

 

 

[fancontrol - pwm1 keeps resetting to 0]

Been having an issue where my idle temps are >60C

The fan will spin for maybe a second or two and then turn off for 10-20 seconds

Checking /sys/class/hwmon/hwmon2/pwm1 and it is set to 0 even though my MINPWM is set to 90

 

Even if I manually tee 90 to pwm1 it will eventually reset to 0 even with fancontrol turned off 

So something resetting without my input...

fan1_input does read fan speed & pwm1_enabled is set to 1

lsof & auditd do not have any info as to what is overwriting the file

 

Only way I can get the fan to stay on is to loop the tee command for a few seconds and then it is on that one speed

Turning fancontrol back on works for a while and changes speed as expected but eventually pwm1 goes back to 0

 

I found that when pwm1 is between 90-125 it does runs fine but once higher than 125 it resets

Then tried 125 as minimum and the working range becomes 125-160 before reset

Then tried 170 as minimum and the working range becomes 175-220 before reset

 

Could the fan be dying and the voltage/load send a signal to the kernel to say "shut down fan"?

tee command to force fan spin (only way to avoid resetting to zero), ctrl+c after a few seconds

while true; do echo 90 | sudo tee /sys/class/hwmon/hwmon2/pwm1; done
