Screenshot of the failed boot
I have a Supermicro X10Dri-T motherboard which fails to boot sometimes. I have tried changing X2APIC setting in the bios but it did not help. In addition, i commented out the EARLY_AP_STARTUP option in the kernel but the issue still remained.
I have attached the screenshot of the failure and logs of the failed and successful boots.
I tried booting with Fedora live cd (Fedora-Workstation-Live-x86_64-25-1.3.iso) and the boot was successful each time.

The culprit was the USB-3 card
xhci1@pci0:129:0:0: class=0x0c0330 card=0x00141912 chip=0x00141912 rev=0x03 hdr=0x00
vendor = 'Renesas Technology Corp.'
device = 'uPD720201 USB 3.0 Host Controller'
class = serial bus
subclass = USB
The cards i tried were the following based on uPD720201 chipset
Mailiya PCI-E to USB 3.0 4 Port PCI Express Expansion Card (PCIe Card)
Rosewill PCI-E to USB 3.0 4-Port PCI Express Expansion Card
Both cause the hangup at boot. After removing the card the system boots up fine.
