I setup netconsole in /etc/init.d/boot.local with:
/sbin/insmod /lib/modules/`uname -r`/kernel/drivers/net/netconsole.ko
netconsole=4444@192.168.10.100/eth0,9353@192.168.10.1/00:03:47:23:e3:df
On the remote machine, I ran the netcat to capture the console:
nodhup netcat -u -l -p 9353 >netconsole.log 2>&1 &
The netconsole.log only captures the following output:
netconsole: local port 4444
netconsole: local IP 192.168....
netconsole: interface eth0
netconsole: remote port 9353
netconsole: remote IP 192.168....
netconsole: remote ethernet address 00:03:47:23:e3:df
netconsole: device eth0 not up yet, forcing it
netconsole: carrier detect appears untrustworthy, waiting 4 seconds
netconsole: network logging started
Disabling IRQ #7
The "Disabling IRQ" message appears about 1 to 2 minutes after netconsole is
initialized and the hang (with no messages) occurs several minutes later,
typically 15 to 30 minutes after booting.
The excessive IRQ #7 activity is associated with sdhci. I have blacklisted the
sdhci driver in /etc/modprobe.d but the lookups still occur with -default. If
I load sdhci manually, it does not receive interrupts unless I access the SD
card. The "excessive" interrupts only occur if the sdhci is auto loaded. This
probably a different issue, but I leave that for someone else to decide.
Since writing the BUG, I have updated to the "official" Beta2 binaries. The
issue is still seen with kernel-default-2.6.22.3-7
Yesterday, I ran kernel-vanilla-2.6.22.3-7 for over 14 hours with no problems.
(I only have the "standard" boot arguments root= vga= resume= splash=). I will
try leave this running all weekend with -vanilla to make sure that this is
solid.
I have tried several boot options with the -default kernel:
pollirq can delay the hang with -default for some time but it still occurs (It
also seems to cause repeated characters when typing.)
nohpet does not prevent the hang on -default.
I am willing to try firescope (hardware/cables should not be a problem). I
just need setup instructions as I have yet to find any sort of HOWTO.
