Public bug reported: 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: [ 0.000000] ------------[ cut here ]------------ [ 0.000000] WARNING: CPU: 0 PID: 0 at /build/linux-Nwr5zx/linux-4.2.0/arch/arm64/mm/numa.c:449 numa_init+0x90/0x398() [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 PID: 0 Comm: swapper Not tainted 4.2.0-14-generic #16-Ubuntu [ 0.000000] Hardware name: HP ProLiant m400 Server Cartridge (DT) [ 0.000000] Call trace: [ 0.000000] [<ffffffc00008a6e8>] dump_backtrace+0x0/0x150 [ 0.000000] [<ffffffc00008a858>] show_stack+0x20/0x30 [ 0.000000] [<ffffffc00086cc7c>] dump_stack+0x7c/0x98 [ 0.000000] [<ffffffc0000bd900>] warn_slowpath_common+0xa0/0xe0 [ 0.000000] [<ffffffc0000bda70>] warn_slowpath_null+0x38/0x50 [ 0.000000] [<ffffffc000c05b40>] numa_init+0x8c/0x398 [ 0.000000] [<ffffffc000c05e7c>] arm64_numa_init+0x30/0x40 [ 0.000000] [<ffffffc000c04b24>] bootmem_init+0x60/0x104 [ 0.000000] [<ffffffc000c052a0>] paging_init+0x198/0x224 [ 0.000000] [<ffffffc000c01e98>] setup_arch+0x274/0x5f8 [ 0.000000] [<ffffffc000bfe6d0>] start_kernel+0xdc/0x3f4 [ 0.000000] ---[ end trace f24b6c88ae00fa9a ]--- ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "console log of crash" https://bugs.launchpad.net/bugs/1502946/+attachment/4484854/+files/my.log ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** No longer affects: cloud-init -- You received this bug notification because you are a member of Yahoo!
