I would suggest you use a mechanism, where you enable printk *only* when you need it like below.
static __always_inline __u32 __readl(const volatile void __iomem *addr)
{
if (some_global_variable)
printk("r bytes 4 addr %p \n",addr);
return *(__force volatile __u32 *)addr;
}
Set the variable through some proc interface or so.
thats what i am thinking to do but i am not sure how to know that it is the console initialisation which is the problem or is it something else.
Also you can then check to see if the printk is failing only at bootup time or everytime. If it still fails whenever you enable it, then you gotta look somewhere else.....
