What Hacker News says?
Just out of curiosity, what kind of issues you have with ARM? Edit: Do you refer to this? https://blog.cloudkernels.net/posts/rpi4-64bit-virt/ Still at least some DMA issues: https://github.com/raspberrypi/linux/issues

HN discussionThe block diagram here: https://blog.cloudkernels.net/static/vaccel_v2/vaccelrt.png#... should probably have some close variant on your home page, I've been around for 20 years and couldn't tell /at all/ what vAccel is. My best guess was something to do with making VMs run faster
