During a crash a 4-port Qlogic adapter may cause an EEH in the kdump
environment due to a race condition between the embedded switch and
the two controllers found in 4 port adapters.
The following errors may be displayed in the console:
EEH: Detected PCI bus error on PHB#23-PE#10000 EEH: This PCI device has failed 1 times in the last hour and will be permanently disabled after 5 failures. EEH: Notify device drivers to shutdown EEH: Beginning: 'error_detected(IO frozen)' EEH: PE#10000 (PCI 0023:01:00.0): no driver EEH: PE#10000 (PCI 0023:02:02.0): no driver
