I found one other person having a similar problem over on the Debian user forums: http://forums.debian.net/viewtopic.php?f=10=130252 Their solution was to update to an experimental 4.8 kernel.

Stretch System Stops Boot Process Immediately After Grub Screen (me too!)
I am having exactly the same problem as Jape Person's post from Oct 22 2016, except my hardware environment is completely different. I am running Debian testing/Stretch 64-bit on a virtual machine under virtualbox. The host OS is Windows 7 64-bit. I don't know exactly which kernel update was the culprit because I got behind on my updates, but I think the problem appeared sometime around 4.7.6 or so. I still have a 4.6 kernel image on the VM so I am able to boot to that just fine. To be specific, after the grub menu disappears the screen goes blank and there is no further activity, no matter how long I wait. Choosing recovery mode in grub does not change anything. Also redirecting the console out a serial port doesn't provide any info -- no serial data is transmitted. I thought this might be a virtualbox compatibility problem, but since someone else is experiencing the same thing on a non-VM machine I now suspect the kernel. Should I post this as a bug somewere, and if so where? Thanks! --Mike Conde

During new installations of Debian my systems I chose: linux-image-686-pae for the i386 systems linux-image-amd64 for the 64 bit systems Those new installations offer me the latest available kernel from the Stretch repository for each type of system. At some time in recent months I installed the linux-image-686-pae on the trouble machine. Since that time it has tracked the latest linux-image package just like the two other i386 systems and the amd64 system. I have seen all of these systems keep the older kernel when a "major" kernel version change has occurred in the repository. In those cases I have kept the older kernel around until I was sure it was okay. But for small kernel version jumps the next reboot just shows me the new kernel, the old one having evidently been replaced. Maybe the time is now opportune for an arch upgrade.

The oldest system in my collection is a Sony Viao video workstation that I believe came with Windows 98 on it. I think it is 17 or 18 years old, and is simply one of the best pieces of hardware of any kind I've ever owned. It has run 24/7 since I purchased it. I'm probably going to buy some Libreboot T400s, or I might get some Intel NUCs, if I think Debian's repositories will support that newer hardware. It's a shame, though, to have perfectly useful pieces like the Panasonic CF-R3 be relegated to obsolete software. The thing is a gem. It's tiny even by modern netbook standards but is fast and powerful. It was a marvel when it was introduced, and it's still no slouch. I appreciate your observations and suggestions. Regards, JP

I am planning to boot from a live image on USB key to try chrooting onto the system drive to fix it. I'll probably try update-grub first just in case something weird happened to grub-pc during that part of the upgrade. I could install a different kernel, but I'd prefer working on the system before doing that to see if there's a way to make the current kernel in testing work. I'm kind of surprised that a minor kernel change of this type (probably) resulted in this problem. I'm not sure just what Debian's policy on kernel upgrades is. With major version changes, I think, the upgrade process leaves the old kernel in place so you can fall back on it if the new one fails. But minor revisions to the kernel just install the new kernel in place of the old one. I only noticed this change in upgrade policy -- if that is, indeed, what it is -- over the past couple of years. This computer is definitely a corner case hardware-wise. The straight replacement of the kernel seems to have backfired in this case for this particular machine. Many thanks for your suggestion.

I'm planning to make a couple of different live images on USB keys so that I can boot the failed system to examine it and see if there's anything I might just fix on it. There were no error messages during the upgrade. I'm a bit more inclined to suspect the kernel upgrade than the grub-pc upgrade. This little unit has a strange hybrid video subsystem which shares system memory with the video subsystem. Everything on the system is early Intel Centrino era stuff, but with the video being ATI. Maybe it's weird enough that it caught a corner case with the kernel change. But the system has been in the rolling-upgrade mode for years, so something odd may have happened to grub-pc itself. I suppose chroot to the system drive and running update-grub is worth a shot. If anyone has a suggestion, I'm willing to try to learn. As I said, it will be a little while before I have time to actually dig into it. In the off chance I actually learn something, I'll post back to the thread. Thanks, JP
