F4-421 Freezes randomly

Post by checor »

Hello,

I've purchased a F4-421 three days ago, and sometimes the NAS stops responding, TOS becomes unavailable and I can't enter ssh. Router says it isn't connected to the local network anymore.

I attached a monitor to discover why this happens, and after a freezes, this was what the monitor show:

It says:

Code: Select all

[drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe A FIFO underrun
It seems that is something related to the CPU. It happened twice today, one time when using TOS, and other on idle.

I'm running TOS 4.2.39. For HDD I'm using a single WD Red Plus new, tested for errors with Smart tools.

Please help me find a way I can avoid my system freezing randomly.

No, I'm using the NAS without modifications.
