Justin, There were no changes in the driver other than to force a 60 second I/O timeout. You probably have a udev rule that was already giving you 60 second timeouts for all scsi devices, so this patch did absolutely nothing. More likely is that there is an I/O pattern change between the kernels that is causing a 3ware firmware issue (or drive firmware issue) on your configuration. I have forwarded your case to 3ware firmware support. -Adam On Tue, Aug 31, 2010 at 5:23 AM, Justin Piszcz <jpiszcz@xxxxxxxxxxxxxxx> wrote: > > > On Tue, 31 Aug 2010, Justin Piszcz wrote: > >> >> >> On Tue, 31 Aug 2010, Justin Piszcz wrote: >> >>> >>> >>> On Sun, 29 Aug 2010, Justin Piszcz wrote: >>> >>>> On Fri, 27 Aug 2010, Justin Piszcz wrote: >> >> Per my earlier message, both cards were resetting, scsi0 and scsi1 under >> kernel 2.6.35(.x), with 2.6.34, the lag problem is gone and my machine is >> back to normal again.
