zpci.1bc6a2 <device name of the function>: Event 0x<PCI event code> reconfigured PCI function 0x<function ID>
Explanation
The availability of a PCI function has changed.
Possible reasons for the change include PCI configuration actions on the
Hardware Management Console or hypervisor.
For shared PCI functions, the function might also have been reserved or
released by another system.
If the device name of a function is shown as 'n/a', the device registration
with the PCI device driver has not completed.
The function ID identifies the function to the I/O configuration (IOCDS).
The PCI event code can be useful diagnostic information for your support
organization.
