Doh! I knew something was wrong with your randconfig :)

#
# Watchdog Device Drivers
#
....

CONFIG_PC87413_WDT=y
CONFIG_60XX_WDT=y
# CONFIG_SBC8360_WDT is not set
CONFIG_CPU5_WDT=y
CONFIG_SMSC37B787_WDT=y
CONFIG_W83627HF_WDT=y
CONFIG_W83697HF_WDT=y
CONFIG_W83877F_WDT=y
CONFIG_W83977F_WDT=y
CONFIG_MACHZ_WDT=y
CONFIG_SBC_EPX_C3_WATCHDOG=y

Kernel was enabling watchdog, with out the userspace having the
heartbeat daemon....

randconfig is really not a good way to test! I can't even ssh to the box
with this config (something else is missing in the config!)

Anyhow, with watchdog removed, it works just fine. (both xsave and non-xsave
kernels)

thanks,
