problems showing up as XFS problems on kernels after 2.6.28-git2

[Danny ter Haar]

I needed the parallel port driver so i compiled 2.6.28-git3 with debug info.
It barfed: http://www.dth.net/kernel/c3/netconsole_2.6.28-git3-d.txt

I re-compiled git2 (with debug support) and <knock wood> so far it is stable:

-------------------
So (in my case) something while going from git2 -> git3 didn't go positive.
If i could get some explanation howto gdb the vmlinux image to determine in what
function the git3 barfed, i would be able to give more info/feedback.
I looked in the Documents folder in the kernel source, i looked at the examples
given there but i really dont understand how/what.
