Well I think I already know what's wrong with my driver - it has
subpage reads broken. So UBI tries to read a subpage, driver fails
there, then it runs a torture test on full PEB that passes (because
page reads work right), marks that PEB as good and retries the subpage
read that fails again, and the story repeats. Does that sound like
reasonable scenario, or do you still want more debugging logs?
