+[8.0.0] Broken icount support on RISC-V
+Description of problem:
+After https://gitlab.com/qemu-project/qemu/-/commit/5a4ae64cac49564354cd6f17598840e4af70e4f5 was merged, RISC-V VMs no longer run with -icount 1 specified in the QEMU arguments. Reverting this commit resolves the issue.
+Steps to reproduce:
+1. Download preinstalled Ubuntu 22.04.2 image from [here](https://cdimage.ubuntu.com/releases/22.04.2/release/ubuntu-22.04.2-preinstalled-server-riscv64+unmatched.img.xz)
+2. Download uboot from [here](http://security.ubuntu.com/ubuntu/pool/main/u/u-boot/u-boot-qemu_2022.01+dfsg-2ubuntu2.3_all.deb)
+3. Extract both.
+4. Run with the command-line specified above.
+Additional information:
+Reading Ubuntu wiki describing how to run RISC-V VMs can help: https://wiki.ubuntu.com/RISC-V/QEMU
