I turned on the following debug:
> CONFIG_DEBUG_SLAB=y
> CONFIG_DEBUG_SPINLOCK=y
> CONFIG_DEBUG_SPINLOCK_SLEEP=y
and now *with* or *without* the following three patches,
it dies during system boot.
proc-dont-lock-task_structs-indefinitely.patch
proc-dont-lock-task_structs-indefinitely-git-nfs-fix.patch
proc-dont-lock-task_structs-indefinitely-cpuset-fix.patch
I will start poping patches until one boots with these
DEBUG options.
My current config has the following options set:
CONFIG_PREEMPT=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_SLAB=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_SPINLOCK_SLEEP=y
CONFIG_DEBUG_MUTEXES=y
The entire failing boot output is:
