[2.5.70-mm7] Badness in local_bh_enable at kernel/softirq.c:117

[Kimmo Sundqvist]

This been with us (or me) since 2.7.65

Someone said something about this having to do with IPv6, but I'm not using it 
now.  It's not even compiled, not in, not as a module.  It was when I tried 
2.5.67 and some other versions.

Btw, sensors-detect adds the following:

i2c_viapro 6028 - - Live 0xfa64f000

And then complains:
Couldn't open /proc/bus/i2c?!? at /usr/sbin/sensors-detect line 2584, <STDIN> 
line 5.

Is this the expected behavior for now?
