netem: kernel freeze using 'gap' option

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I tested the netem queuing discipline and everything worked except the 
reordering of packets. The kernel freezes. This happened with kernel version 
2.6.8.1 (with Ingo Molnars voluntary preempt patch -P9) and 2.6.9-rc4-mm1, 
thats why I assume that the netem module is the reason for the freezes.

Could anyone test whether the command below will result in a kernel freeze:

'tc qdisc add dev eth0 root netem delay 10ms gap 5'
(or in 2.6.8 syntax 'tc qdisc add dev eth0 root netem latency 10ms gap 5')

If there is anything I can do, please let me know.

Thanks

Markus
