i just enabled it while trying to find out the cause of my problems.
My actual config has:
# grep -i 'DEBUG' .config|egrep -v "^# "
CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC=y
CONFIG_SLUB_DEBUG=y
CONFIG_HAVE_DMA_API_DEBUG=y
CONFIG_X86_DEBUGCTLMSR=y
CONFIG_PNP_DEBUG_MESSAGES=y
CONFIG_AIC7XXX_DEBUG_ENABLE=y
CONFIG_AIC7XXX_DEBUG_MASK=0
CONFIG_AIC79XX_DEBUG_ENABLE=y
CONFIG_AIC79XX_DEBUG_MASK=0
CONFIG_OCFS2_DEBUG_MASKLOG=y
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_SHIRQ=y
CONFIG_SCHED_DEBUG=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
CONFIG_DEBUG_LOCK_ALLOC=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_MEMORY_INIT=y
CONFIG_DEBUG_RODATA=y
CONFIG_KEYS_DEBUG_PROC_KEYS=y
my original config had:
# grep -i 'DEBUG' .config_stillnotworking|egrep -v "^# "
CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC=y
CONFIG_HAVE_DMA_API_DEBUG=y
CONFIG_X86_DEBUGCTLMSR=y
CONFIG_PNP_DEBUG_MESSAGES=y
CONFIG_AIC7XXX_DEBUG_ENABLE=y
CONFIG_AIC7XXX_DEBUG_MASK=0
CONFIG_AIC79XX_DEBUG_ENABLE=y
CONFIG_AIC79XX_DEBUG_MASK=0
CONFIG_OCFS2_DEBUG_MASKLOG=y
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_SCHED_DEBUG=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_MEMORY_INIT=y
CONFIG_DEBUG_RODATA=y
CONFIG_KEYS_DEBUG_PROC_KEYS=y
With both configs i'm seeing the SAME symptoms after a while.
Which options should i disable?
Stefan
