U-Boot 2012.07 (Sep 21 2012 - 14:54:04) Instead, sometimes I get: Freeing init memory: 176K pre-reboot sd 2:0:0:0: [sda] Synchronizing SCSI cache Restarting system. Reboot failed -- System halted To reproduce, I created an initrd that just has busybox and a simple /init sh script that just reboots. I set a node to persistently boot "pxe", and constantly served the same kernel and initrd, for a constantly cycling test. On affected kernels, this reproduces within around five reboots. Impact: when this strikes, MAAS fails to deploy nodes. MAAS needs three reboots to fully deploy nodes, so the MAAS failure probability is higher than a single reboot failure. This will cause great difficulty when using nodes at scale.
