Hi folks,
I installed 2.6.9-rc4 this morning, but it died at boot time
(a lot of hex output and something about "Aiee" :-). I tried
to redirect syslog to another host, but the error message did
not show up in the foreign log files.
Any idea how to catch this message? The problem seems to be
reproducable, and I would be glad to help.
Regards
Harri

Serial console or pen and paper.

Use a null modem to the other system and boot with
console=ttyS0,baudrate
Then use some logging terminal program (e.g. kermit)
on the other side to catch the output.
Before doing this verify in a working system that the cable works.
If that is not possible you can use a digital camera in the worst
case and put the jpeg somewhere.

I disabled ehci_hcd.ko in the boot procedure and loaded
it manually when syslog was running. This was written into
kern.log:

If I keep ehci_hcd in the boot procedure, then the
kernel dies immediately after printing these messages.
In my test environment there was no crash, though.

You need to use netconsole, serial console or some other technique to
get the panic info over to another machine. Please mail again with info
on what you do to get the panic and the info that comes out of the panic
itself. I'm sending you the netconsole text.

This module logs kernel printk messages over UDP allowing debugging of
problem where disk logging fails and serial consoles are impractical.
It can be used either built-in or as a module. As a built-in,
netconsole initializes immediately after NIC cards and will bring up
the specified interface as soon as possible. While this doesn't allow
capture of early kernel panics, it does capture most of the boot
process.
It takes a string configuration parameter "netconsole" in the
following format:
netconsole=[src-port]@[src-ip]/[<dev>],[tgt-port]@<tgt-ip>/[tgt-macaddr]
where
src-port source for UDP packets (defaults to 6665)
src-ip source IP to use (interface address)
dev network interface (eth0)
tgt-port port for logging agent (6666)
tgt-ip IP address for logging agent
tgt-macaddr ethernet MAC address for logging agent (broadcast)
Examples:
linux [email protected]/eth1,[email protected]/12:34:56:78:9a:bc
or
insmod netconsole netconsole=@/,@10.0.0.2/
Built-in netconsole starts immediately after the TCP stack is
initialized and attempts to bring up the supplied dev at the supplied
address.
The remote host can run either 'netcat -u -l -p <port>' or syslogd.
WARNING: the default target ethernet setting uses the broadcast
ethernet address to send packets, which can cause increased load on
other systems on the same ethernet segment.
NOTE: the network device (eth1 in the above case) can run any kind
of other network traffic, netconsole is not intrusive. Netconsole
might cause slight delays in other traffic if the volume of kernel
messages is high, but should have no other impact.
Netconsole was designed to be as instantaneous as possible, to
enable the logging of even the most critical kernel bugs. It works
from IRQ contexts as well, and does not enable interrupts while
sending packets. Due to these unique needs, configuration can not
be more automatic, and some fundamental limitations will remain:
only IP networks, UDP packets and ethernet devices are supported.
