http://bugzilla.kernel.org/show_bug.cgi?id=11898 ------- Comment #34 from vandrove@xxxxxxxxxx 2008-11-11 03:28 ------- Two news, both bad. First bad news is that I tried kernel (yesterday's git) with patch from #28, and on 4 runs I twice got kernel crash I attached, once system hung during test for no aparent reason, and one run completed. Second bad news is that one run which completed took twice as long when compared to test with Jens's patches to SATA reverted (4x 50MBps vs. 4x 24MBps). But that probably deserves separate bug once crashes are fixed - with 2.6.27-rc1 during my test (write 4GB concurrently to all devices) all 4 leds for devices behind PMP are on. With current git and patch above almost always only one led is lit, usually for 2-3 seconds, then bandwidth shifts to another drive - as drives have 60MBps speed while sata has 300MBps, no surprise it is slower when commands are not interleaved... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
