I recently upgraded my firewall box from 4.4 to 4.6. At first it was
running well (about a week), but yesterday I started getting occasional
hangs where the screen would be blank and it'd stop responding to ping
(and passing traffic). Figuring it was a hardware failure, I swapped
the drive into another box. I still seem to be getting occasional
hangs; I even turned off screen blanking, and when it hangs there's
nothing on the screen (monitor goes to power save). The only shared
hardware between the two machines is a Compaq fiber em NIC (which I'll
replace tonight) and the hard drive (which isn't showing any errors).
Assuming it is a software problem, how can I diagnose it? I'll paste
the dmesg below. I'm running 4.6 with patch 001 and 002 applied, and
I've tried both the sp and mp kernels.
