It sounds like you've reproduced the problem on a non-RedHat kernel, so can you open a report at http://bugzilla.kernel.org using an unmodified upstream kernel, please? Please attach "lspci -vv" output (as root) from before the problem and another from after, as well as the complete dmesg log. You mention several other bugzilla reports; please include URLs to those as well. You mention "taking down PCI bus"; what specifically do you mean by that? I do see some FFFFFFFF data from ata7 and ata8 in your dmesg, which can be a symptom of a device not responding. ata7 and ata8 seem to be on 06:00.0, and your lspci shows UnsupReq+ set in that device's AER Capability. Please also attach "lspci -xxxxs06:00.0" output so we can look at that in more detail. The atl1c device is at 03:00.0, and your lspci also shows UnsupReq+ for it, so please also attach "lspci -xxxxs03:00.0" output. Does your kernel have CONFIG_PCIEAER=y? If not, can you turn that on and see if you see anything useful in dmesg when the problem occurs?
