From time to time, big file copy (hundreds of MB) hang, but it's a rare event. For testing I've just copied a couple of files for a total of 3.5 GB with some speed issues. Speed was > 10 MB/s over a 100 mbps ethernet for the major part of the transfer, then dropped down to 5 MB/s after ~2 GB (only for the bigger of the two files). I didn't investigate about possible roles of the LAN switch, though. > The resetting message as you have in log usually means that is some is wrong > with FW/HW - mei driver not receiving reply in timely manner. > > To debug it future, you can enable dynamic debug for mei driver : > echo -n 'module mei +lfp' > /sys/kernel/debug/dynamic_debug/control > echo -n 'module mei_me +lfp' > /sys/kernel/debug/dynamic_debug/control > and wait for next reset > Thanks for the info. Once I enable debug, what should I look for? Thank you.
