Thanks for the reminder! I just realized Ubuntu 20.02 was already released on 4/23. We should try it. For the CPU firmware (CPU microcode?) update issue: sorry, it's completely out of my scope -- I only work on Linux. Hopefully that issue will be resolved in the near future. -- You received

Sorry, I made a typo above: systemd.dsystemd.default_standard_output=kmsg ==> systemd.default_standard_output=kmsg. BTW, it looks systemd.show_status=true makes no difference for me. I don't see any status info during the boot-up time -- not sure if I did something wrong. -- You received this

I don't have much knowledge bout systemd, either :-) I just did a "man systemd" and found the options of systemd. "man systemd" says that we can use pass these kernel parameters to systemd: systemd.service_watchdogs=true systemd.show_status=true systemd.log_level=debug

Since Alt-SysRq-w gives nothing, I'm sure the long delay is not a kernel/driver issue but a user space issue. It looks due to some reason I just can not reproduce the long delay. :-( In the Hyper-V Virtual Machine Connection window's "View" menu, there is an item "Enhanced Session". In my Ubuntu

I also tried xrdp mode and the VM booted up to the xrdp login window in 14 seconds, which is faster than the "native Xorg GUI mode" (which needs 30s) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu.

It looks #48 shows some service is causing the long delay -- can you try 'systemctl list-jobs' to see active jobs, as the "Hint" says? :-) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu.

@msgallery: BTW, you mentioned 'The "restart" button is not functional' -- actually it is not functional only when we try to click the button by mouse -- if we press Tab to focus on the button and then press Enter, the VM should reboot. :-) I'll try to mention this to Hyper-V team, but I'm not

BTW, my Linux kernel version is 5.3.0-46-generic #38-Ubuntu (17:37:05, 3/27/2020). The "graphic artifact" is somehow caused by the "$vt_hanoff" kernel parameter (check "cat /proc/cmdline"). If I manually remove the "$vt_hanoff" at the grub screen, I won't see the "graphic artifact" -- Ubuntu
