well, bug obviously in the printk, where the format was %ld (now %llu).
chances are, that your kernel sector_t and drbds sector_t are not of
the same size
though I don't think that you could load that module then...
If it would be loadable, that would result in all sorts
of unexpected behaviour...

maybe the assert is just not correctly expressed...

but if you can reproduce this, and you are sure that both drbd module
and kernel have the CONFIG_LBD set, I'd be interessted to hear about the
circumstances in more detail, since then indeed it might be a drbd bug ...
