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.
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.
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.
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.
