I have posted some information to bugzilla (see [0]), but not with
pci=earlydump. It seems that bugzilla doesn't want to mail me a reset
e-mail, but while I am waiting, I posted this on my homepage (see
[1]).

Please, note that this boot log was taken with the patch that I
e-mailed earlier (i.e., the one that makes things work). If you want
me to send a log with a vanilla kernel, just let me know and I will
grab more information.


Thanks,
RogÃrio.
