Hello all,
Just looking for a bit of guidance here and a suggestion on proper
next steps. I think there may be an issue within the below broadcom nand
driver implementation.
I have an Asus GTE-AX11000 and it reboots\crashes multiple times a week,
upon inspection of snmp logging you can see the below entries, when the
kernel panic occurs the entire router locks up, and sometimes reboots.
Sometimes it doesn't reboot and the router hangs completely and drops
all network devices, and removes wireless SSIDs and all of your devices
lose their connection.
Not sure who to turn to but Asus support has not grasped the gravity of
this problem and I am thinking this can only really be resolved with a
firmware\driver\linux update, so just hoping for some additional help or
guidance from this group.
Thanks much.
