comment:1 Changed 23 months ago by anonymous

Had a similar issue on my WRT1900AC @4.4rev48975 where my load average goes batsh*t crazy after some flapping ISP outage and never wanted to reconnect again. Had to power cycle the router.

comment:2 Changed 23 months ago by anonymous

The original report looks like an out of memory condition.

comment:3 Changed 23 months ago by anonymous

This issue can be reproduced when idle, I suspect it's not related to out of memory IMO.

comment:4 Changed 23 months ago by anonymous

<4>[55108.711649] netifd: page allocation failure: order:5, mode:0x24000c0

The message above is clearly an out of memory error.

comment:5 Changed 23 months ago by anonymous

install a clean image only with LuCI, I can also reproduce when just booted without doing anything.

It works the first time.
