Created attachment 438437 [details] the patched code Description of problem: i've been told that it wasn't testing the i/o accurately because it was choosing its starting location as a random number of bytes into the disk, then the most of the time you will need to read two sectors to get 512 bytes. only if you choose a starting byte divisible by 512 will you read your whole 512 bytes from a single sector. Using direct i/o with memory and buffer alignment fixes this issue as well. One of my colleagues (Mr. Ian Sherratt) patched this, so i don't have a good understanding of the code. I've attached the patched version Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. just running the test 2. 3. Actual results: n/a Expected results: n/a Additional info:
