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. -- Package-specific info: ** Version: Linux version 6.1.0-21-amd64 (debian-kernel@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.90-1 (2024-05-03) ** Command line: BOOT_IMAGE=/boot/vmlinuz-6.1.0-21-amd64 root=UUID=db4a3fee-0b7b-4120-b0fb-9e87c31c4f6b ro quiet ** Not tainted ** Kernel log: Unable to read kernel log; any relevant messages should be attached ** Model information sys_vendor: Microsoft Corporation product_name: Virtual Machine product_version: Hyper-V UEFI Release v1.0 chassis_vendor: Microsoft Corporation chassis_version: Hyper-V UEFI Release v1.0 bios_vendor: Microsoft Corporation bios_version: Hyper-V UEFI Release v1.0 board_vendor: Microsoft Corporation board_name: Virtual Machine board_version: Hyper-V UEFI Release v1.0 ** Loaded modules: tls binfmt_misc nls_ascii nls_cp437 vfat fat intel_rapl_msr intel_rapl_common ghash_clmulni_intel sha512_ssse3 sha512_generic sha256_ssse3 sha1_ssse3 aesni_intel crypto_simd cryptd rapl hyperv_drm serio_raw drm_shmem_helper pcspkr drm_kms_helper hv_balloon hyperv_keyboard hv_utils evdev sg joydev drm fuse loop dm_mod efi_pstore configfs efivarfs ip_tables x_tables autofs4 ext4 crc16 mbcache jbd2 crc32c_generic sd_mod t10_pi sr_mod crc64_rocksoft cdrom crc64 crc_t10dif crct10dif_generic hv_storvsc scsi_transport_fc hid_generic scsi_mod hid_hyperv hid hv_netvsc scsi_common crct10dif_pclmul crct10dif_common crc32_pclmul crc32c_intel hv_vmbus ** PCI devices: ** USB devices: not available -- System Information: Debian Release: 12.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.1.0-21-amd64 (SMP w/4 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages linux-image-6.1.0-21-amd64 depends on: ii initramfs-tools [linux-initramfs-tool] 0.142 ii kmod 30+20221128-1 ii linux-base 4.9 Versions of packages linux-image-6.1.0-21-amd64 recommends: ii apparmor 3.0.8-3 ii firmware-linux-free 20200122-1 Versions of packages linux-image-6.1.0-21-amd64 suggests: pn debian-kernel-handbook ii grub-efi-amd64 2.06-13+deb12u1 pn linux-doc-6.1 Versions of packages linux-image-6.1.0-21-amd64 is related to: pn firmware-amd-graphics pn firmware-atheros pn firmware-bnx2 pn firmware-bnx2x pn firmware-brcm80211 pn firmware-cavium pn firmware-intel-sound pn firmware-intelwimax pn firmware-ipw2x00 pn firmware-ivtv pn firmware-iwlwifi pn firmware-libertas pn firmware-linux-nonfree pn firmware-misc-nonfree pn firmware-myricom pn firmware-netxen pn firmware-qlogic pn firmware-realtek pn firmware-samsung pn firmware-siano pn firmware-ti-connectivity pn xen-hypervisor -- no debconf information
