Does this patch limit the speed? I fought with this same problem for a couple of months and discovered that limiting the speed would stop the panics, but it made the device so slow as to be useless for my purposes. For example, if I attached the device to an ohci controller, I never had any problems. If I attched it to an ehci controller, but set the debugging sysctl variables high enough to force the traffic to slow down, I never had any problems (except for filling up my system message log with garbage). If your patch can stop the panics without limiting the speed of the device to something like 2Mbs then great!! :)Received on Thu Jul 01 2004 - 17:08:13 UTC
