guest hangs after use ethtool to set scatter-gather on
On the guests, i have a rtl8139 nic, I use ethtool to set scatter-gather on ( ethtool -K eth0 sg on ),
after that, at host side, I use scp to send a file into guest. As a result, guest hang.
At that point qemu is using 100% of one host CPU, about 100% guest.
If guest is centOS6.5， with no problem.
The guest system is Fedora release 19(Kernel 3.11.10-200.fc19.x86_64).
host system is debian 7.1.
Kernel:3.10.0
Qemu: 2.3.0
cmd:

Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU and Fedora? Or could we close this ticket nowadays?
[Expired for QEMU because there has been no activity for 60 days.]
