Hi Michael,
Thank you for your many advice and the Vadatech engineer helped how to delete “pci_mrfevr.ko” delete.
Now mrfioc2 IOC successfully loaded and running at the uTCA PMC platform.
[root@amc725 ~]# cd /lib/modules/3.10.0-229.rt56.162.el6rt.x86_64/extra/
[root@amc725 extra]# ls
daq_series.ko mrf.ko pci_mrfevg.ko pci_mrfevr.ko sm750fb.ko
[root@amc725 extra]# rm pci_mrfevr.ko
After reboot...
[root@amc725 ~]# lsmod | grep mrf

제목: RE: mrfioc2 error at uTCA platform
Hi Michael,
When boot time automatically loaded SLAC MRF "pci_mrfevr".
[root@amc725 ~]# lsmod | grep mrf
mrf 13648 0
uio 19175 1 mrf
parport 40636 1 mrf
pci_mrfevr 53687 0
I manually removed.
[root@amc725 opt]# /sbin/rmmod pci_mrfevr
[root@amc725 opt]# lsmod | grep mrf
mrf 13648 0
uio 19175 1 mrf
parport 40636 1 mrf
Restarted mrfioc2 but same error.
mrmEvrSetupPCI("PMCEVR",0xe,1,0)
Device PMCEVR 14:1.0
Using IRQ 16
Failed to open uio device for PCI device 0000:0e:01.0: No such file or directory
Failed to enable interrupt
How do I disable/remove this "pci_mrfevr" ?

This shows that both kernel modules are loaded. To simplify
troubleshooting please ensure that only the 'mrf' module is loaded and
not 'pci_mrfevr'.
Only one linux driver can be attached to a particular PCI device. This
will typically be the first one loaded, in this case 'pci_mrfevr'. I
should also note that, with modern Linux drivers, having to manually
create a file in /dev/ is a sure sign that something is wrong.
