I'm working with CentOS Linux kernel version 3.10.0-1160.49.1 and I also noticed that kswapd0 runs for over 20 seconds and seem to cause a kernel panic. In examining the kswapd() code, it has an infinite loop. It can only break from this loop if the function, kthread_should_stop() returns as true. This function tests the current task's flag for the bit KTHREAD_SHOULD_STOP is set. This bit will only be set if a call to to_live_kthread() that will get a pointer to the current kernel thread. If the pointer is NULL, then the KTHREAD_SHOULD_STOP bit will not be set. This may be the problem with this BUG.
