Title: Network dies on big transfers
Post by: lekter on March 30, 2004, 05:25:45 am
I have a big problem. When I make big transfers to my 760 (a bunch of mp3 for example) the network dies. It usualy happens at 20Mb aprox, but it varies. Does anyone have similar problems?

Zaurus side:
  - Cacko QTopia Latest (also tried with X11 and the newest pdaXrom)
      - Hapens even just after flashing without installing any app

Linux side:
  - Gentoo (usbnet)
      - It happens with 2.4.x, 2.6.0, 2.6.1, 2.6.2 and 2.6.3 kernels

lekter, I\'m having the same problem.  I started a thread (here: <http://www.zaurususergroup.com/index.php?name=PNphpBB2&file=viewtopic&t=2817>) but no one has had any input.

As you\'ll see, I have a completely different set-up.  This seems to support my earlier conclusion that the problem is in the Z\'s usb networking sub-system.  It looks like a pretty serious problem.  I don\'t have the time to dig into the kernel for a fix.  I\'m hoping someone already knows what\'s going on.

BTW, which xfer protocol are you using?  I\'ve seen the problem occur with ftp, sftp, and scp.  Also, where are you uploading to?  My tests thus far have been only to SD.  I\'ve been meaning to test uploading to CF and RAM but I haven\'t had the time yet.

There seems to be a serious problem with Cacko\'s kernel in both roms. This issue doesn\'t happen with the standard kernel as far as I remember nor with openzaurus.

I have been looking into a problem with usbnet, but there isn\'t a problem there.

During some time I suspected that there were a problem with fbvncserver, but I tried with a clean flash and it failed too.

Transfering to memory works better, because it is slower I think. The main problem is with SD (and CF too), which are faster than main memory.

Did someone found a fix for this problem?
