Subject: 2.6.0-test10: Badness in local_bh_enable at kernel/softirq.c:121
Date: Wed, 26 Nov 2003 11:42:43 +0100	[thread overview]
Message-ID: <20031126104243.GA1395@amber.kn-bremen.de> (raw)


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
Call Trace:

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.

Regards, Christian
