So while I slept I ran a test kernel with that swapops BUG replaced with a printk. I'm not sure of the validity of this, given the state of the kernel afterwards is somewhat suspect, but I did see in the logs this morning.. [18728.075153] migration_entry_to_page BUG hit [18728.200705] BUG: Bad rss-counter state mm:ffff880241b3f500 idx:0 val:1 (Not tainted) [18728.200706] BUG: Bad rss-counter state mm:ffff880241b3f500 idx:1 val:-1 (Not tainted) This might be collateral damage from the swapops thing, I guess we won't know until that gets fixed, but I thought I'd mention that we might still have a problem here.
