Now one wrinkle about it being a linux-azure bug: if you _aren't_ seeing this on bionic but _were_ seeing it on cosmic, then there must be something else involved, because I believe (based on the publishing history[0]) that cosmic was on the same kernel version as bionic.
This could, of course, still be a kernel bug that's just not hit by bionic's userspace. But, to be sure of where we stand, can you confirm the statement in the original report that this was an issue on cosmic? Do you have enough test history to determine when this started happening?
