Well, the machine must have started with some kernel. What mainline

The last booted kernel was a 2.6.25 based kernel. I am trying to find out
the last good kernel.org kernel. I should have that information by tomorrow.

I tried few older kernels till 2.6.28 and all of them had the
same problem.
I also tried using SLUB instead of SLAB. That also failed to

Dang it, that's my fault. Thanks for catching it Sachin.
I assumed pseries always enabled EEH, but I see now you can disable it
if you have EMBEDDED set (which your config does).
It's a bit yucky making the MSI code depend on EEH, but the only other
option would be to pu

Now, it would be nice if you guys stopped sending stripped down dmesg...
