hi !
I have now run 2.6.23-rc4-rt1 on my arm920t with the pi_stress test programm
from http://people.redhat.com/williams/tests
My question if I run the pi_stress, my watchdog triggers, if watchdog is
disabled i get this:
Admin threads running on processor: 0
Test threads running on processor: 0
Starting PI Stress Test
Number of thread groups: 10
Number of inversions per group: infinite
Test threads using scheduler policy: SCHED_FIFO
Admin thread priority: 4
10 groups of 3 threads will be created
High thread priority: 3
Med thread priority: 2
Low thread priority: 1
Press Control-C to stop test
Current Inversions: 15551
Keyboard Interrupt!
Stopping test
Total inversion performed: 15570
Test Duration: 0 days, 0 hours, 0 minutes, 14 seconds
Is this the correct behaviour ? Or does it show a problem ?
thanks, regards
fred
