All,
I've got a quick question about the stack trace below. I see the
flags <IRQ> and <EOI> in this trace and would like to understand
better what this means.  My swag is that it's showing that the stack
trace is running in interrupt context when the kernel panic'd.
<IRQ> is 'Interrupt Request', <EOI> is "End Of Interrupt'.
(ret_from_intr is called after handling an interrupt)
[arch/<arch>/kernel/entry_{32/64}.S]

Yes, looks like your kernel panic'd while in interrupt context.
(netif_receive_skb is called from NET_RX_SOFTIRQ handler, and it is in
bottom-half context, but acc. to your stack trace
it looks like it has been interrupted by an interrupt, but that should
be fine.)

Correct me if i am wrong

Anyway, thanks in advance for the help ... Cheers, node1 kernel: <IRQ> [<ffffffff8021f155>] netif_receive_skb+0x2b7/0x2d7
