Sergey, thanks for looking into this already! > John, do you see any of these problems on your test machine? For x86 I have only been using qemu. (For hardware tests I use arm64-smp in order to verify memory barriers.) With qemu-x86_64 I am unable to reproduce the problem. Lianbo, thanks for the report. Can you share your boot args? Anything special in there (like log_buf_len=, earlyprintk, etc)? Also, could you share your CONFIG_LOG_* and CONFIG_PRINTK_* options? I will move to bare metal x86_64 and hopefully see it as well.
