All computers unable to boot to fog; web interface down

[mecsr]

I came in today and our fog machine is having all kinds of problems:

1. None of our department’s computers are able to boot into the fog network interface. On boot, the computers are able to find the right server IP. iPXE initialising devices… returns ok. tftp://FOGIP/default.ipxe… returns ok. But then, http://FOGIP/fog/service/ipxe/boot.php… returns “Input/output error (http://ipxe.org/1d0c6439)”. This prevents it from booting into fog.

2. When looking at what the fog machine actually displays on screen, it says:

[     8.967992] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
[     8.968006] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

When I Googled this error, I found multiple places that said to run sudo fsck -f /dev/sda2, which is actually what we had to run a few days ago when fog went down, but this time it’s not working.

3. Maybe this is the root of the problem, but our web interface is also down.

Any help to fix these issues would be much appreciated! Thanks in advance!
