Thanks and Best Regards

Hi! A web-search of:
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
returns lots of interesting things (I'm learning too!)
Do any of them 'fit' [&help] your environment?

Best wishes....

Hi Jjanel, there was a defective card and once replaced this msg went away


Thank you and I am sorry it took me so long to respond.

Kind Regards
