Leif Asbrink leif at sm5bsz.comHello Anton, It is not only your system. I tried Debian Jessie with the 3.10-2-amd64 kernel. I follow the same procedure that works rock stable in Wheezy: Open 8 terminal windows. Start top in the 8th window. Then start rtlsdr (I use Linrad) One dongle for each terminal window. I have 7 dongles and they work all glitch-free in Wheezy at 2.4 MHz with a total CPU load of about 40% on a 8 core machine with 4667 bogomips. If I have only a single dongle connected to the computer it works under Jessie, but if I have two or more the system crasches. If I open terminals first when needed I can run three dongles, at least some times, but with all the terminal windows open the system crasches already when I try to get the first dongle running. I have seen 100.1% CPU load from udevd as well as kworker/4:1 and other kworkers. There is no way out except the reset switch. The Debian bug report system is too complicated so I am not able to file a report to the developers. They assume I have configured exim4 or remember the details of my mail accounts.... It seems to be a severe bug so I guess they get reports from others. / Leif On Mon, 12 Aug 2013 18:55:22 +0400 Anton Komarov <anton.komarov at gmail.com> wrote: > Tested several rtl dongles with linux 3.9.1 on Debian Jessie (testing) > and got disappointing results > 2 dongles simultaneously working ok > if using 3 or more than 3rd dongle not working (1st and 2nd working ok) > > in Debian Wheezy i did manage to run 5 dongles simultaneously (kernel 3.2) > i suppose developers should pay attention to than fact. > -- > public PGP key > http://pastebin.com/dqZqgyVE
