It's barking on mdelay(5000) which is a debug thing (when you pass
'fake_sleep' to the kernel, it will stop 5 seconds in there then wakeup
instead of letting the PMU shut the CPU down, it's useful for debugging
driver sleep code.

It shoud not be failing on this though:

#define mdelay(n) (\
(__builtin_constant_p(n) && (n)<=MAX_UDELAY_MS) ? udelay((n)*1000) : \
({unsigned long __ms=(n); while (__ms--) udelay(1000);}))

The __builtin_constant_p(5000) && (5000)<=5 test should fail thus
turning into a loop of udelay(1000). Your gcc seems to be screwing
it up. What version are you using ?

The current bk snapshot I have here doesn't have a problem at this line.

I'll check that out, thanks.
