This brings back memories of the venerable old bug #75681
We're booting precise systems with the linux-image-generic-lts-saucy kernel (3.11, as you'll see in the attached boot log), and have some specialised SSD devices we RAID together to form a single block device. Unfortunately, the md autodetection and assembly seems to happen before all of these devices have reported in, causing a halted boot sitting at a busybox prompt (not fun for servers!)

As a workaround, we set scsi_mod.scan=sync in the kernel boot options, which makes boot block on the scsi scan. I'm not sure that's the best solution, but it felt the most appropriate at the time! |
