Subject: linux-next 20110831 - netconsole startup issue
Date: Thu, 01 Sep 2011 11:14:39 -0400 [thread overview]
Message-ID: <5187.1314890079@turing-police.cc.vt.edu> (raw)
Chasing a kernel panic in linux-next, and hit an unrelated issue
starting up netconsole that's bogging me down.
On linux-next-20110823, I had this:
[ 7.078099] e1000e: Intel(R) PRO/1000 Network Driver - 1.5.1-k
[ 7.078102] e1000e: Copyright(c) 1999 - 2011 Intel Corporation.
[ 7.078158] e1000e 0000:00:19.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
[ 7.078171] e1000e 0000:00:19.0: setting latency timer to 64
[ 7.078354] e1000e 0000:00:19.0: irq 46 for MSI/MSI-X
[ 7.269439] e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 00:21:70:de:b6:fd
[ 7.269443] e1000e 0000:00:19.0: eth0: Intel(R) PRO/1000 Network Connection
[ 7.269469] e1000e 0000:00:19.0: eth0: MAC: 7, PHY: 8, PBA No: 4003FF-0FF
[ 7.293569] netconsole: network logging started
Bring up the ethernet, then the console. Works great,
However, on -20110831, I get this:
[ 0.983149] netconsole: local port 9909
[ 0.983254] netconsole: local IP 128.173.14.107
[ 0.983358] netconsole: interface 'eth0'
[ 0.983461] netconsole: remote port 9909
[ 0.983564] netconsole: remote IP 128.173.14.108
[ 0.983668] netconsole: remote ethernet address 00:14:22:5a:79:d3
[ 0.983776] netconsole: eth0 doesn't exist, aborting.
[ 0.983897] netconsole: cleaning up
[ 1.176429] e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 00:21:70:de:b6:fd
[ 1.176557] e1000e 0000:00:19.0: eth0: Intel(R) PRO/1000 Network Connection
[ 1.176688] e1000e 0000:00:19.0: eth0: MAC: 7, PHY: 8, PBA No: 4003FF-0FF
Whoops. No netconsole.
Even more annoying (and quite possibly related), the kernel is built with
CONFIG_NETCONSOLE_DYNAMIC. On -20110823, I have a /sys/kernel/config/netconsole
directory and can use it to configure netconsole on the fly. However, on
-20110831, /sys/kernel/config is empty - no netconsole subdirectory. So I
couldn't even boot to single-user, configure netconsole, and then continue to
multiuser and capture the crash.
