Action Timed Out?

I keep getting this error in various places on one of my CCRs. Is there some way to force a reinstall (this is happening in some places that are covered by the system package)? Is the onboard flash failing? An upgrade did not fix it and rebooting doesn’t fix it. Shutting down and physically cycling power are the only things that allowed that upgrade, too.

We only caught that something was still wrong after we realized that DNS requests from clients were timing out.

Try to netinstall .. http://wiki.mikrotik.com/wiki/Manual:Netinstall
this will reformat your nand and do a system fresh install

Sadly, netinstall refuses to work. I booted the router with a serial terminal attached, set it to boot from ethernet, then exited the menu and powered it down. Started netinstall, set the address, set “net booting”->“boot server enabled”, connected an ethernet cable to the only enabled port (same subnet as the address above), powered the router, and it never finds the boot server. I’m at a loss for what to do at this point…
