SubjectPROBLEM: e100 or e1000 on SMP kernel freeze system (ipx+ncp)
Test on last driver e1000 5.2.52 (from intel.com)...
And get same result....
NAPI enable / disable not important...

"ip link set eth0 down" may be replace Instead of "connect cable to NIC".
And get same result... (w/o message "NIC Link is Up").
