How stable is the development kernel?

["N. Nordman" <_nino_(_at_)_home_(_dot_)_se>]

Hi,

It seems I would need to recompile my kernel to -current in order to get 
functioning linux compability. So I just wanted to know how stable one can 
expect the -current kernel to be. I realize there's no guarantees of any sort 
and that one might except problems. But exactly what can I expect, i.e. 
approximately how unstable is the -current kernel...

Even if stability is relative, anyone got any info on running a kernel 
snapshot and encountered problems etc etc?

Thanks,
