@Shay: thanks. Do you happen to have a reproducer that just involves
running an lmbench subtest? I tried the following, but didn't observe a
hang:
Host A:
ubuntu@ubuntu:~$ /usr/lib/lmbench/bin/bw_tcp -s
Host B:
ubuntu@ubuntu:~$ /usr/lib/lmbench/bin/bw_tcp -P 224 <HostA> 2048M
0.065536 82.65 MB/sec
** Changed in: lmbench (Ubuntu)
Status: New => Incomplete
