Bug description:
There has recently been a tremendous uptick in the number of crashes
being reported about iproute2 since 2015-07-27. This was initially
noticed as the phasing of the iproute2 package in -updates for 14.04
(SRU bug 1470091) was stopped. Its worth noting that the same
increase in crashes was not detected with the Vivid SRU.
Additionally, it appears that the increase in crash rate is unrelated
to the iproute2 SRU as it occurs with the version of the package in
the release pocket or the updates pocket for 14.04.
The following is a database query showing the quantity of crashes on a
daily basis about the iproute2 package for the version of the package
in the release pocket and then the updates pocket.

Notice the increase starting on 20150728 for the old version of the
package. I've reviewed the individual crashes from 20150729 and all
of them (regardless of the iproute2 package version) were using the
following kernel version. I'd attribute the drop in crashes on
20150801 and 20150802 to it being the weekend.
3.13.0-59-generic
Unfortunately, all the crashes from the iproute2 package are
incomplete / corrupt so there isn't much to go on. Here is one
example crash:
https://errors.ubuntu.com/oops/331373ac-3596-11e5-9ed9-fa163e22e467
I'll add all the OOPSes from 20150729 as an attachment if somebody
wants to have a look at them. I'm also happy to run more queries of
the OOPSes to see if we can determine a pattern.
