Yeah disabling lockdep by removing PROVE_LOCKING from omap2plus_defconfig makes n900 LCD work for me again. Not getting any lockdep warnings during boot with lockdep enabled though. So basically the following patch makes LCD work on n900 with omap2plus_defconfig. Tomi, got any ideas? > Ok, it works now. I was doing tests in daylight so it was poorly > visible. The right part of keyboard stays lit (but that's expected > AFAICT), but the left part blinks. During idle, both should go off and are doing so for me. Both LEDs off indicates off mode, left LED off is for retention mode. So you still have something blocking off mode, maybe check: echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode Regards, Tony 8< ------------------- --- a/arch/arm/configs/omap2plus_defconfig +++ b/arch/arm/configs/omap2plus_defconfig @@ -472,7 +472,6 @@ CONFIG_DEBUG_INFO_DWARF4=y CONFIG_MAGIC_SYSRQ=y CONFIG_SCHEDSTATS=y CONFIG_TIMER_STATS=y -CONFIG_PROVE_LOCKING=y # CONFIG_DEBUG_BUGVERBOSE is not set CONFIG_SECURITY=y CONFIG_CRYPTO_MICHAEL_MIC=y
