5021 - it is my thread ID
[1]
Application with GUI + pfring = problem ?
"zcount" works without any extra messages , in my application always is
this message.
[2]
Before and after message "BUG: soft lockup - CPU#0 stuck for 22s!"
pfring functions works ok, no dropped packages etc...
[3]
I always start 4 threads , but message "BUG: soft lockup - CPU#0 stuck
for 22s!" is show only for first thread .
Anyone have any idea or suggestion ?
