I have managed to reliably reproduce the issue on a QEMU VM (on a host with nested virtualisation enabled). Here are the steps: 1. Install gvisor as per https://gvisor.dev/docs/user_guide/install/#install-latest 2. Run $ for i in $(seq 1 100); do sudo runsc --platform=kvm --network=none do echo ok; done I've tried to recompile the kernel with the above patch, but unfortunately it does fix the issue. I'm happy to try other patches/fixes queued for 5.16-rc4
You can find them already in the "for-linus" tag of kvm.git as well as in the master branch, but there isn't much else.
