Yep, it seems to definitely be loaded. Did you have bfq as the default scheduler for mmcblk0, if so then setting it on mmcblk1 wouldn't change anything in /syspart.. it's also possible that bfqio is enabled regardless of whether bfq is or not, and just sits idle until called upon. Ok, could you please try one of these (depending on your setup - the modules should be unchanged), I have disabled the "queue small requests" part of BFQ v2 r1 and have been running it happily on my device for a full day without any crashes..
