Looks weird.
What is the kernel version? Does the 'dis' command work for other functions?
You could do a check on one of the instructions - the 'bl' comes to
mind. Not sure, but I believe it should amount to:
0xeb000000 | (((0xc049fe34-0xc015a2f0) >> 2) & 0x00ffffff)
i.e.
0xeb0d16d1
Is that what you get with
crash> rd 0xc015a2e8
?
If not, try a
crash> search 0xeb0d16d1
and see if it turns up somewhere else.
