Minor update - it's not only Azure's. AWS m5.8xlarge and m5.16xlarge (32 and 64 cores) fail similarly. I'll try later also QEMU machines with different amount of CPUs.Test on QEMU machine with 31 CPUs passes. With 32 CPUs - failure as reported. dmesg is empty - no error around this. Maybe something with per-cpu variables?
Can I get y'alls .config? I ran it on one of my 80cpu boxes and it didn't reproduce on my new code or on 5.12. Thanks, Josef
