Unplugged and plugged in boot USBs system now freezes during boot

[kaseypocius]

Hey All, I have a modest freenas system I've been running for about a month, I needed to move it so I powered it down and unplugged the boot USBs. Now when I try and boot the system it starts the freenas boot, but hangs - console image below. I have tried using the hw.pci.realloc_bars=1 in the enviroment config, but no luck there either. Not sure if something went wrong in the BIOS, the CMOS battery is old and this console read makes me wonder if there's something changed in the BIOS since the last boot, but I can't find it. I'm a little anxious about updating the BIOS, as I know this version has worked well up until now. Any help is appreciated.

My system specs are as follows

Mobo GIGABYTE GA-Z77X-UD5H LGA 1155 CPU Intel i-2600k Memory 32 GB (4 x 8GB) CORSAIR Vengeance DDR3 1600

Closed - fixed some setting in the BIOS in terms of legacy USB support - all good now
