I suffer from this bug too, with this card in access point mode:
02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1]
(rev 73)
Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070]
And kernel 4.15.0-33-generic on Ubuntu 16.04 Xenial, though I
encountered it with previous versions too, and I think with 4.4 kernels
too.
It seems to happen when the load on the network is high.
But luckily, according to https://www.spinics.net/lists/linux-
wireless/msg169581.html it seems to be fixed in Intel by
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-
iwlwifi.git/commit/?id=b8e2a319df8cc60626ab7dcabbbab64ff56be41e in their
release/core35.
I think the resulting bug is probably in iwlwifi.ko (linux-image-extra package)
(I don't think it is in iwlwifi.ucode).
Is there any way to track which release/coreXX is in a kernel version?
