Have an unexpected display configuration problem while checking the BSP on new hardware.
When the display resolution is changed the screen blanks as per normal, but then does come back to show the Accept/
Revert popup. The new display resolution can be blindly accepted as works OK after a forced reboot.

Basic 650 installation is OK.
650SP1 is OK
An ifs created with the BSP is OK, with no patches.
With full patches the fault is witnessed and the following errors logged:-
pci_init: found PCI device 8086:f31
io-display: aperture shm_ctl failed! (0x00000000)

/usr/photon/bin/io-graphics: gf_dev_attach('/dev/io-display/8086,0f31,0'): gf errno 7
phgrafx: restart.status = 0, restart.n_devices = 1
phgrafx: 0: vid=0x8086,did=0xf31,deviceindex=0 = [0: No error]
VGA primary : bus 0x0 dev/func 0x10
Found 1 PCI/AGP display devices
pci_init: found PCI device 8086:f31
io-display: aperture shm_ctl failed! (0x00000000)

Given the patches do not include any graphics drivers with the libc* libraries only applied the resolution change still 
works as expected, but with procnto included in the ifs the problem occurs.
Is this a known issue with a workaround?
