Stretch System Stops Boot Process Immediately After Grub Screen
I've got a little Panasonic CF-R3 mini-laptop which has been
kept fully up-to-date in testing every day since Etch was
released. (I think the original installation is that old.)
I've been using the linux-image-686-pae kernel on the system.
The updates today included an update to
linux-image-4.7.0-1-686-pae (4.7.8-1) and grub-pc (2.02-beta3-1).
Upon reboot the system stops with a blinking underline cursor in
the upper left corner. I suspect that the boot process stops
immediately after grub. I cannot connect via ssh or even ping
the system. Using Ctrl-Alt-Del has no effect, but touching the
start-stop switch elicits a beep and immediate power-down.
The same results are obtained if I use the grub menu to select
A much older desktop system running testing and the same kernel
was not adversely affected.
I'm only reporting this for purposes of corroboration in case
anyone else has seen something similar coincident with these
I'm in the midst of some business which will prevent me from
delving into the failure right now. I'll get into it some time
next week, perhaps.
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
