Smells like slab corruption to me, and the problems may end up being then largely random just depending on who ends up using the allocation that gets trampled on.
I wouldn't be surprised if it's all the same thing - including your network issue.
Both you and Guenter seem to be seeing this on that google cloud VM setup, which may or may not be related. I haven't seen any reports from anybody else, but that might still be just coincidence.
But it makes me go back to your original report, where you suspected the virtio pull.
Looking at that original report, and doing
gitk 7ebfc85e2cd7..69dac8e431af
nothing else looks all that relevant, although obviously any random error path could end up doing a double free and messing up the slab cache that way. But a lot of the non-virtio stuff there is things like RISC-V and devicetree that definitely shouldn't have any effect.
Adding Michael Tsirkin to this thread too, just so he knows.
Linus
