rcu_sched detected stalls on CPUs Sending NMI from CPU 43 to CPUs 14 watchdog: BUG: soft lockup - CPU#26 stuck for 22s [migration/54:335] ixgbe 0000:19:00.1 eno2: initiating reset due to tx timeout
The BUG should have caused a stack traceback which would have told us where the CPU was stuck for 22 seconds. That's usually not a starvation issue, it's more often a deadlock (or livelock) condition where the thread on CPU#26 was waiting for something to happen, and it never happened.
