dmitrygr2on Building the worst Linux PC ever: 6 hours to boot Ubuntu

Please note what I said. I release interrupts after every byte READ/WRITTEN, so that the maximal delay to a refresh is the length of a single byte read/write. In case it wasn't clear, the only interrupt in use is the ram refresh interrupt. If it is masked, and triggers, it will execute the handler when it is unmasked. This means that even a loop on RAM read/write will not starve RAM of refreshes

[also, why do I keep being told I am submitting too fast, please slow down. I just posted 2 comments here, that is all. Had to make a new username :(]
