[ 0.140013] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
This is: [ 0.000000] Linux version 4.15.0-33-generic (buildd@lgw01-amd64-038) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #36-Ubuntu SMP Wed Aug 15 13:44:35 UTC 2018 (Ubuntu 4.15.0-33.36-generic 4.15.18)
Switching to a 64-bit kernel allows boot to proceed.
I cannot include output of the commands you request (uname, version_signature, dmesg, lspci) because the guest doesn't boot. The above kernel output is from a just-installed clean guest however. |
== SRU Justification ==
After an upgrade to Bionic, the bug reporter states the 32-bit kernel
does not boot under Xen PV mode. This bug does not affect 64-bit
kernels and if fixed by mainline commit 6a92b11169a6.
== Fix ==
6a92b11169a6 ("x86/EISA: Don't probe EISA bus for Xen PV guests")
== Regression Potential ==
Low. This commit only affects x86 kernels. This commit has also been cc'd to upstream stable, so it has had
additional upstream review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
After the most recent 18.04 32-bit upgrade of linux-image-generic, it now refuses to boot under Xen PV mode:
