[Bug 509239] Re: network (eth0) doesn't work after suspend to ram (Marvell 88E8036)

[Eduardo]

Hi. I have confirmed where is the bug. With git bisect I have seen that:

eduardo at eduardo-laptop:~/linux-git$ git bisect bad
c82f63e411f1b58427c103bd95af2863b1c96dd1 is first bad commit
commit c82f63e411f1b58427c103bd95af2863b1c96dd1

    PCI: check saved state before restore

    Without the check, the config space may be filled with zeros. Though
    the driver should try to avoid call restoring before saving, but the
    pci layer also should check this.

    Also removes the existing check in pci_restore_standard_config, since
    it's superfluous with the new check in restore_state.

axx, Do you have exactly the same error? Can you check (with "git
bisect") if this commit causes your problem?. You can comment at
bugzilla of kernel.
