Description houwenwu 2025-11-27 11:46:37 UTC 
Description of problem:

The load average remains approximately 1.0 even when the system is completely idle. The ps command reveals that the [load_calc] thread is in an uninterruptible sleep state. If executing  `echo 0 > /proc/async_load_calc`, the load average will return to zero later.


Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1.echo 1 > /proc/async_load_calc
2.don't run any tasks, wait 15min
3.cat /proc/loadavg 

Actual results:
cat /proc/loadavg
1.00 1.00 1.00 1/226 19461

Expected results:
near zero load average
