I've got a WRT1900acs V2 here that i got given, it seems to stop working after 5-10 mins regardless of if in use or just turned on with nothing connected,
It had stock linksys on p1 and DD-wrt on P2 both seemed to lock up the router after certain time.
Had spare time today so decided to connect serial, i seem to think this is the problem before it crashes it gives Internal error: Oops: 80000007 [#1] SMP ARM from putty output. (from a quick google this looks like a kernal panic?)
i have tried flashing stock on both partitions with tftp but still seems to do the same,
just wondered if anyone could shed some light on the issue?
is there a command i can run from putty/serial to completely clean nvram and reflash again? (if indeed its a kernal panic i thought cleaning nvram may work, must add i have tried lots of resets and erase nvram from normal putty window not serial coms port window i mean)
i have enclosed full putty output and ive xx:xx mac adresses
