Hi all, I am using kernel 2.6.14.6-grsec (x86_64 on AMD Sempron 64) with QoS (HTB) Occasionally, when pppd drops a connection I see this in syslog : Mar 25 13:40:17 myserver pppd[1300]: No response to 3 echo-requests Mar 25 13:40:17 myserver pppd[1300]: Serial link appears to be disconnected. Mar 25 13:40:17 myserver pppd[1300]: Connect time 1250.6 minutes. Mar 25 13:40:17 myserver pppd[1300]: Sent 971616622 bytes, received 1884313787 bytes. Mar 25 13:40:20 myserver pppd[1300]: Connection terminated. Mar 25 13:40:30 myserver kernel: unregister_netdevice: waiting for ppp0 to become free. Usage count = 358 Then only force reboot of the machine solves the problem. I found very similar problem with same symptoms : http://groups.google.com/group/linux.debian.kernel/browse_thread/thread/dcb36b5fe827fad6/05445a30be147608 Do you have any ideas how I can debug why dev->refcnt did not reach zero? regards, Martin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
