I'm told 0day does *some* suspend/resume testing, but I think it's pretty limited, partly because the kinds of machines it primarily works on don't really support suspend/resume at all. I'm also not sure just how many of those machines are 32-bit at all.. But I'm adding Zhang Rui to the cc, to see if my recollection is right. Because you're right, more suspend/resume automated testing would be good to have. And yes, people test mainly 64-bit these days. Also, I'm not even sure what the 0day rules are for just plain mainline. I don't tend to see a lot of breakage reports, even though I'd expect to. This came in from the x86 trees (and those do their own tests too, but probably not suspend/resume either), but it hit my tree fairly soon after going into the x86 -tip trees. Linus
