System is 4.2-STABLE or -RELEASE. what works: - UP kernel with or without NFS activity on all interfaces - SMP kernel without NFS (client) activity on all interfaces - SMP kernel _with_ NFS (client) activity on fxp1 or fxp2 What do not work: - SMP kernel _with_ NFS (client) activity on fxp0 (Symptoms: message "SCB Timeout", NFS related activities locked hard. All other non NFS related network activities keep running). Hope this may help. RN. IhM To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
