Title: support compressed kernels on arm64 Status in debian-installer package in Ubuntu: Fix Released Status in flash-kernel package in Ubuntu: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux-hwe-edge package in Ubuntu: New Status in debian-installer source package in Xenial: Fix Committed Status in flash-kernel source package in Xenial: In Progress Status in linux-hwe-edge source package in Xenial: New Status in flash-kernel package in Debian: New Bug description: [Impact] Ubuntu kernels >= hwe-y (4.8) will no longer boot on xgene/uboot systems. The image size appears to have outgrown the defined firmware region, and u-boot will error out with a checksum mismatch error. A solution for this is to start shipping a compressed kernel (Image.gz target). flash-kernel needs updating to detect a compressed kernel and set the appropriate uImage compression flag. Similarly, d-i needs updating because it does it's own uImage generation. [Test Case] Boot an hwe-y kernel on an xgene/uboot system (APM Mustang, HP ProLiant m400). [Regression Risk] The necessary code is in place and in-use for yakkety, and no issues have been discovered there. The SRU involves clean cherry-picks of that code for d-i & f-k. The kernel side needs to be modified to pull in the correct version of flash-kernel for xenial.
