Nothing changed, I've been running evl ps loops here as well and did not
notice any weirdness of that kind, this does not look good since the ABI
did not change with these latest fixes.

Generally speaking, evl ps extracts all the information it displays from
/sys device files, as published by the real-time core. Could you check
the values exported for threads manually? e.g.

root@homelab-qemu-x86_64:/sys# cat /sys/devices/virtual/thread/Thread2/wchan 
Event1
