9. Patch: More Stability for Raspberry Pi
Code:
nano /boot/cmdline.txt
add the parameter
Code:
slub_debug=FP
( no new line! )
press Ctrl + o , Return, Ctrl + x to save changes



Manfred slub_debug is a bad idea. It will slow down your hashrate by 20%. I've tried it Wink. you should switch to BFGMiner.

I have never heard anyone else having a slowdown from this command.  I have always gotten around ~360kh per miner at 850mhz with or without slub_debug.

Please provide more info!

well to be honest I was using slub_debug=FPUZ not FP ... the latter didn't have any effect (PI still crashes). But FPUZ worked but was showing lower performance (on remote pools) local hashrates were showing 360kh/s per unit as always ofcourse, but I don't think it's submitting shares at that rate. for example on a 10 unit I got around 2.5 mhs compared to 3.4mhs without (but crashes)

In the end I didn't use slub_debug but did a
Code:
sudo BRANCH=next rpi-update

Which solved all my crashing problems.

Maybe my problem was related to raspbian. Scripta is using a different OS I think?
