dmesg from 2.6.35-rc5

I had problems reproducing the bug after a ureadahead reprofiling didn't work. After rebooting with the Ubuntu kernel which is apparently set up to work with ureadahead, I can now reproduce it again. I attach another dmesg output, since the signature is a bit different this time (but is still the same bug I guess?)

I won't pretend that I understand these things...

Now that I can reproduce the bug again, I will go back to testing older kernels (but it is time consuming, since it doesn't happen on every boot).
