Title:
kernel crash on m400 arm64 server cartridge
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Wily:
Fix Released
Bug description:
We've made some progress on bug 1499869 , such that on Friday I actually had
successful installs.
An attempt at an install today shows a kernel stack trace early in the boot,
then the initramfs not finding any network devices and thus failing to mount
the iscsi root.
The trace looks like this:
