You can try running the machine with the kernel option "pcie_aspm=off"
and see if that helps and also try to disable C-States or Power Saving
all together in the BIOS.
More Details here:
I've experienced lock-ups in the past because of these issues. The
network device hung because it tried to go into power saving mode using
ASPM and it failed and whole servers locked-up after being idle for a
while because of a bug in Intel Processors regarding the deeper power
saving modes (C-States) although these are supposed to be fixed since
6.3. Hope this helps.
