That 176 is WIN_SMART, but you had earlier WIN_SMART commands that worked ok, so it's something specific that triggers it. data_phase = 1 is TASKFILE_IN. So try to see if you get to ide_error(), which is where Bartlomiejs latest patch was in effect - but add a few printk's there to print out the 'stat' variable etc to see if it actually triggers. And maybe a WARN_ON(1) to get the trace..
