Kernel panics "skb_over_panic" at random intervals

1 3027
Hi all,

I'm using Bananian 15.01 and for a couple of weeks now I've been experiencing kernel panics at random intervals, most of the time I get 1-2 per day but sometimes up to 3 and sometimes there are none for a couple of days. Once this happens I have no access to the banana pi anymore and it stop responding to ping, I only use it as a network unit and therefore I have no keyboard/mouse nor monitor connected to it. I do however have a printer connected to one of the usb ports but the crashes happen even when the printer is turned off.

When the kernel panic happens the red led on the banana pi board shuts off and the blue led is constantly lit and the green one occasionally blinks and this goes on until I reboot the unit. Sometimes I get syslogd messages when the crash happens but not always and when I do get the messages it's always about skb_over_panic:

I've also noticed something odd/interesting; when the pi freezes my entire LAN stops working for a couple of seconds and I am even unable to ping my router.

I'm still experiencing these seemingly random crashes but I'm starting to suspect that it has something to do with Samba because the last time when the Banana Pi crashed was when my Win7 desktop computer had just booted into the desktop. At that moment I had no other connections going on to the Banana Pi except for Samba. Also, like I said in my previous post, it seems that all network connections die for a few seconds (at least) on my Win7 pc when the Banana Pi crashes.
