[SOLVED] ODD stability problem

[jugi]

Hello!

I have had strange freezing problem (everything freezes halts) after while even normal non overlocked raspberry. No traces in log.

Hardware version seems to be one of the first china patch 512 Mb version.

I'm using lates xbian with atp update /upgrade (no other stuff, extra devices etc).
I'm using decent 2A over 5V power source and some basic genue scandisk memory card (16 GB) 4 class.
Default speed, no overlocking.

It drove me crazy until i found these SD card stability crash preventation instructions.

If you want to experiment, I'd suggest playing with:
init_emmc_clock (default 100000000)
from config.txt.

and
sdhci-bcm2708.emmc_clock_freq (default 100000000)
from cmdline.txt.

I would suggest these to be added as stability patch / ready option as it seems to make more SD cards compatible and prevent random chrashes.

i tried it now 800 Mhz core / 400 GPU and 400 ram with overvolt 6 with no problems with HD video.

I will no test the stability and try actually overclok it i will report further.

Best, Jukka
