Synopsis: [msk] watchdog timeout State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Mon Oct 25 19:17:29 UTC 2010 State-Changed-Why: I also have a DGE-560T but I can't reproduce this issue on my box. Because you said disabling MSI fixed the issue I vaguely guess it could be a silicon bug which controller sometimes looses Tx completion interrupts or could be trggered by inappropriately programmed event timer for the controller. It seems Yukon II controllers are very sensitive to internal timer values so it can also trigger the issue. I don't have permanent solution for these issues but you can try the patch at the following URL. http://people.freebsd.org/~yongari/msk/msk.watchdog.diff It does not fix the issue but it will show watchdog timeout message and tries to recover from that ranther than completely resetting controller. If all goes ok, it sometimes shows watchdog timeouts but it wouldn't reset controller such that you can treat the watchdog timeouts as information message.
