Message-ID: <20061017135013.19302.qmail@web57810.mail.re3.yahoo.com> Date: Tue, 17 Oct 2006 06:50:12 -0700 (PDT) From: John Philips <johnphilips42@...oo.com> To: linux-kernel@...r.kernel.org Cc: linux-net@...r.kernel.org Subject: BUG: warning at kernel/softirq.c:141/local_bh_enable() Hi, I recently upgraded some router/NAT devices from 2.4.25 to 2.6.17.8. They're using VIA C3 processors and NatSemi DP83815 NICs. Right after the upgrade I started noticing these error messages on one of the heavier-loaded boxes. This particular box routes and does NAT for around 400 users, peaking at 6Mb/sec of throughput. The errors were happening about every 3-5 minutes. I statically set eth6 to 100baseTX-FD with mii-tool, and now the errors appear every few hours for 10-20 minute stretches. I searched Google and couldn't find any insight (FYI, I'm NOT using the CIPE patches). Any ideas?
