With the current kernel I suddenly get the following error displayed during boot: e1000e: Intel(R) PRO/1000 Network Driver - 1.0.2-k2 e1000e: Copyright (c) 1999-2008 Intel Corporation. e1000e 0000:00:19.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 ! e1000e 0000:00:19.0: pci_enable_pcie_error_reporting failed 0xfffffffb e1000e 0000:00:19.0: setting latency timer to 64 e1000e 0000:00:19.0: irq 26 for MSI/MSI-X
This looks to be the consequence of: commit 68eac4602b9104cdaa6c18b3edd914cececa6a1e Author: Xiaotian Feng <dfeng@redhat.com> Date: Fri Aug 14 14:35:52 2009 +0000 e1000e: fix use of pci_enable_pcie_error_reporting
Looking at the change it seems logical that this error, that I previously only saw during resumes from suppend to RAM, now also shows up during system boot. So I don't think it can be qualified as a regression, but it is certainly rather annoying.
Questions: - is it possible that the error occurs due to a kernel bug, or is this certain to be due to broken hardware? - as the error is non-fatal, should it maybe be changed from dev_err to dev_info, so that at least it does not show up during a boot with 'quiet'? - if broken hardware is common, should the kernel complain at all, or at least maybe show a slightly "friendlier" message?

I can provide full dmesg and kernel config if desired.
