Description

When I'm using Transmission on VU+ box (tuxbox, mipsel - Enigma2 based satellite receiver) I'm loosing completely network connection after a while mainly during heavy uploads (more it seems to be related to a number of connections then upload bandwidth) and more simultaneous downloads.

In the messages log I see repeating very often following error and after some time network connection on the box goes down:

DMA Sep 27 18:01:59 bm750 user.crit kernel: No Rx Descriptor, disabling rx 
DMA Sep 27 18:01:59 bm750 user.crit kernel: No Rx Descriptor, disabling rx 
DMA Sep 27 18:02:00 bm750 user.crit kernel: No Rx Descriptor, disabling rx 
DMA Sep 27 18:02:00 bm750 user.crit kernel: No Rx Descriptor, disabling rx 

This error occurs only in case I'm running Transimission, it disappear when I exit it, usually after some time, sometimes also full reboot is needed.... I know it might be pretty hard to give any advice here, however - at least trying it. I posted question also on forum, but no advice there and I believe this might be some bug maybe in the transition itself.

Version : enigma2-plugin-extensions-transmission_2.33-r0_mipsel.ipk

Linux version 2.6.18-7.3 (linux@linux) (gcc version 4.4.3 (GCC) ) #1 SMP Tue Aug 23 00:01:55 CEST 2011

I searched for that error, however authors of that image confirms that related option in the Kernel should be enabled already (http://www.vuplus-support.org/wbb2/thread.php?threadid=20635)

enable CONFIG_BCMINTEMAC_7038_STREAMING=y kernel option on all broadcom based dreamboxes this fixes stability issues on upload (No Rx Descriptor, disabling rx DMA in kernel log)

Seems I'm not alone with that problem - http://www.i-have-a-dreambox.com/wbb2/thread.php?postid=1395709#post1395709 (in German - same problem on Dreambox ).

This problem appears during last 6 months on all versions of Transmission I've been using.

Thank you.

Some cursory Googling indicates that this is a stability problem in Dreambox which is triggered by network activity, rather than a bug in Transmission.

You should probably report this bug to the Dreambox maintainers for another opinion.
