I've seen the same error when trying to work around vprintk issue on i386 with CONFIG_EXPERT=y CONFIG_EARLY_PRINTK=n instead of fixing 'printk.c' I've changed 'include/linux/printk.h:95' -void early_vprintk(const char *fmt, va_list args); +asmlinkage void early_vprintk(const char *fmt, va_list args); and compiled with CONFIG_EARLY_PRINTK=y. Not sure if that is an option on ARM. Herman has reported the latter issue earlier today. ciao, robin
