Bug#1071584: linux-image-6.1.0-21-amd64: power cycle on hypervisor Hyper-V (2016) during bootup

[m0x7e <xm0x7e@gmail.com>]

Package: src:linux
Version: 6.1.90-1
Severity: normal
X-Debbugs-Cc: xm0x7e@gmail.com

Dear Maintainer,

I've installed Debian 12.5.0 via net-install on a Hyper-V 2016 (2024/05 updates installed) machine. The installation went well, but as soon as the machine tried to boot up with the 6.1.0-21 kernel, it always was resetting after starting the initramfs sequence.

Unfortunately all debug options (debug=, debug, removing quiet/splash) didn't work out to get ANY useful log. Interesting side note: after 2-3 retries the boot is sometimes successful and the OS seems to be stable up (at least 2-3 hours as far as I tested).

The fall-back Kernel 6.1.0-18 works fine. Coming up all the time with each retry.

Here I've recorded a sample: https://www.youtube.com/watch?v=jE53r7ulTKw

I've seen that there were others reporting issues with 6.1.0-20/21 kernel, but the focus there seems to be 3rd party software or hardware related.

A possibly related bug is #1071378 while adding the parameter earlyprintk=vga didn't change anything.
