[Bug 48264] Re: Kernel Crash [Debian or Kernel.org kernels OK]

What I usually do is download the latest kernel from kernel.org, then
make oldconfig, then run make-kpkg to make the packages. So at one point
the oldconfig was probably based on the ubuntu kernel config but I may
have changed a few settings here and there over the years.

How can I get the stack trace output with the latest kernel? It seems
that things are crashing before any kernel panic (as can be seen in the
dmesg output). If I'm in the console I can see some of the output when
the kernel locks up but at that point the system is frozen and the LEDs
on the keyboard are blinking.

I tried to ouput dmesg to a file in a loop :

while test 1; do for i in {1..10}; do dmesg > /mnt/dmesg_$i.txt; sleep
1; done; done

but it must have crashed or stopped too because the trace didn't make it
into one of the files.
