Bug#823543: Kernel-image-4.5 amd64 does not boot; kernel 4.3 only boots in recovery.

[Jonathan Polak <jpolak@gmail.com>]

Package: src:linux
Version: 4.5.1-1 AND 4.3.5-1
Severity: critical
Justification: breaks the whole system
System type: Lenovo X230 

Distro: Debian Testing

I was using kernel 4.3.5-1 because neither kernel 4.4 nor 4.5 booted normally. (See bug 819597). Between May 2 and May 4 I Upon updating the following packages ​

 installed_pkgs.txt

​

Upon rebooting on May 5 kernel 4.3 threw a kernel panic and did not boot. See image in this link: ​

 dump 4.3.pdf

​ 

Attempting to boot into kernel 4.5.1-1 also resulted in kernel panic at boot

See image in this link: 

 kernel 4.5.pdf

​

 Booting in recovery with kernel 4.5 results in identical kernel panic. ​

 dump 4.5 recovery.pdf

​

The only way to boot was kernel 4.3 recovery. I salvaged the EFI dumps from the boot fails - they are appended here: ​

 dumpA-4.5.txt

​​

 dumpB-4.5.txt

​A is txt and B is binary. Both were from a failed 4.5 boot.
