No, it's atually when I'm 'uploading' from my laptop to my server.
One interesting thing is that my server is running lvm2 with snapshots,
which makes writes slower than my laptop can push data over the network, so
it's definitely causing buffers to fill up.
I just did a download test and got 4.5MB/s sustained without problems.

So, do you recomend I try this if my problem is with TX and not RX?
More generally, is there a tip you have for me to get WCHAN in ps on a
process that is causing this problem, or will sysrq-W/sysrq-D show this, or
do I need something like sysrq-T ?
I just reproduced this while having a loop that did
while :; do date; echo w > /proc/sysrq-trigger; sleep 30; done
I got a nice 30mn (!) hang, including the lines below:
