GPU fails showing up after reboot

[KingHawk]

I've had many problems this week so I'm looking what to do now.
Short summary of what happened:

- wednesday eve sudden crash of unraid (no logs);

- thursday morning raid-1 ssd pool shows curruption errors and GPU falling off the bus for first time (rebooted as fast fix);

- thursday afternoon again ssd pool curruption errors and GPU falling off the bus;

- thursday eve updated unraid from .6 to .8, no immediate errors, after that and I've run a scrub with error fix but this didn't find any errors;

- friday morning GPU falling off the bus, no corruption errors.

I've just rebooted hoping the GPU would show up again but it didn't.
I got a lot of errors like these (are they related?):

Mar  1 14:57:30 JJ-SILVERSTONE kernel: pci 0000:06:00.0: BAR 7: failed to assign [mem size 0x00100000 64bit]

Everything was running fine after switching to the new GPU a while ago so I wonder what changed that would make it so that the GPU started falling off the bus and even stops showing up completely.
Looking forward to any help in fixing these issues.

I've managed to fix the BAR failed to assign warnings with the following settings in BIOS:
1) Above 4G Decoding - ENABLED
2) Re-Size BAR Support - ENABLED
3) SR-IOV Support - ENABLED
4) Hot-Plug Support - DISABLED
 

I've also added 'pci=realloc=off' to '/boot/syslinux/syslinux.cfg' as described here:

So now I'll just wait and see if everything stays stable with this setup.

Sadly still having trouble with the GPU falling off the bus after working normally for 22 hours.
