Hello Rafael,

the regression has been solved for 3.0 by disabling the problematic code here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=f483d3923dc3a6394c483e28ccb3fe700bdf399e

When the new commandline argument 'pci=realloc' is not set (which is the
default) the buggy code is disabled.

Therefore this bug can be closed on the 2.6.39 -> 3.0 regression list.

Thanks,
Oliver
