Strange, but I don't have all the config options that you have, or I
cannot yet find the right things to turn them on. Specifically I'm
missing

My current Kernel hacking section:

# CONFIG_PRINTK_IGNORE_LOGLEVEL is not set
CONFIG_DEBUG_KERNEL=y
CONFIG_MAGIC_SYSRQ=y
CONFIG_LOG_BUF_SHIFT=17
# CONFIG_DETECT_SOFTLOCKUP is not set
# CONFIG_SCHEDSTATS is not set
# CONFIG_DEBUG_SLAB is not set

I'll build this way for now. Send back some info on what you think I
need to turn on. I'm using make menuconfig. Maybe that's the problem?

Thanks,
