Title:
  [ARM] Reboot sometimes fails on highbank

Status in The Eilt project:
  New
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Reproduced on:

  Linux version 3.2.0-30-highbank (buildd@chort) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #48-Ubuntu SMP PREEMPT Fri Aug 24 20:04:03 UTC 2012 (Ubuntu 3.2.0-30.48-highbank 3.2.27)
  Linux version 3.2.0-32-highbank (buildd@musimon) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #51-Ubuntu SMP PREEMPT Thu Sep 27 00:36:21 UTC 2012 (Ubuntu 3.2.0-32.51-highbank 3.2.30)

  Evidently does not affect:

  Linux version 3.5.0-16-highbank (buildd@shedir) (gcc version 4.7.2
  (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #25-Ubuntu SMP PREEMPT Sat Sep 29
  01:44:21 UTC 2012 (Ubuntu 3.5.0-16.25-highbank 3.5.4)

  When I use busybox's reboot command, I usually get:

  Freeing init memory: 176K
  pre-reboot
  sd 2:0:0:0: [sda] Synchronizing SCSI cache
  Restarting system.

  
  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.
