Comment 25 for bug 1561830

Yes, your test kernel fixes the bug. I ran a test before installing it, and the bug happened rapidly at the start of the benchmark test on the Samsung HD103UJ drive. Then I installed your reverted kernel, rebooted and ran six benchmark tests without any failures. Previously, it has always failed on the first or second benchmark test if it was ever going to fail.

I noticed that the benchmark results for the read speed of the drive are a little lower with the patch reverted, down from about 103 Mbytes/s to about 97 Mbytes/s. The write speeds seem unaffected at about 100 Mbyte/s. So it looks like whatever the reverted code is doing is producing a worthwhile read speed increase.
