Subject: Kernel crash in 2.6.39-rc2-wl
Date: Wed, 06 Apr 2011 13:30:42 -0700 [thread overview]
Message-ID: <4D9CCD72.7020308@candelatech.com> (raw)
This is from today's wireless-testing kernel, with a few non-tainting
patches related to wireless stuff. In general, 39-rc2 seems pretty
flaky, but on this boot, this is the first kernel splat.
I had reloaded our user-space network-config DB, which would have deleted
and created some VETH and MAC-VLAN interfaces, and a bunch of
protocol sockets, virtual-routers (xorp with unique routing tables) etc.
