See below fix. Please test it. Thanks in advance, Wim. [WATCHDOG] Fix pcwd_init_module crash Fix for the problem detected by Ingo Molnar: enabling CONFIG_PCWATCHDOG=y crashes bzImage bootup. The reason for this can be found in drivers/makefile We first do: obj-y += char/ and later we do: obj-y += base/ block/ misc/ mfd/ net/ media/ So if we put a platform or isa or usb bus driver in char/watchdog (which is called from the Makefile in drivers/char/Makefile) then we didn't have the different device drivers initialized yet (they are in drivers/base and drivers/usb and ...) This fix makes sure that we compile the watchdog drivers after drivers/base, drivers/misc, drivers/pci and drivers/usb. We also do the compile after hwmon because in the future the watchdog temperature support will use the hwmon system.
