bingo with classic rcu
Congratulations Yannick!
So, it seems mainly RCU vs. timer(?) problem. I send CC of this message
to RCU author, linux-kernel and netdev lists.
Interesting! Any chance of a pointer to the original messages?
A quick Google search and a look at LKML showed me nothing. :-/
Thanx, Paul
I'm not sure how much time you
could/will to offer for this debugging.
Anyway, if it's possible I think it would be interesting to check with
CONFIG_PREEMPT_RCU = y again, but CONFIG_HOTPLUG_CPU = n ("Processor
type and features --> Support for suspend on SMP and ...") in the
meantime.
Many thanks,
Jarek P.
