2.6.0-test10: Badness in local_bh_enable at kernel/softirq.c:121

[Christian Schlittchen]

When trying to establish a ppp/pppoe connection I get the following
and the connection fails:

Badness in local_bh_enable at kernel/softirq.c:121

This is 100% reproducible with any kernel version since at least 2.5.71
I tried. I tried to recompile the kernel with different settings and
compilers, but the error stays the same.

I can provide more information if needed.
