Hi all,

We noticed that the Efika sometimes does not start from the first time. Symptoms are a constant green led after powering up without disk activity.
I've uploaded a kernel (link below) which fixes this issue. It's a hack for now, and is not yet in the kernel repo so use it as-is for the time being.

You can look at the diff linked to below to see the changes. If you're wondering if it's only the additions of printk() statements, you are correct. There appears to be a timing issue somewhere and the printk()'s add enough delay for it not to occur. We'll trace down where exactly the issue is, but due to other priorities this is not very high on the todo list...

Hi.

Yes, it's also needed on ArmHF. Be aware that there are some video playback issues with the kernel I linked above. We're looking into that...

On my Efika (received yesterday) 'sometimes' does not quite hit the spot. Roughly on every second boot I observe this symptom.

Besides, does this kernel supersede the one provided by markos on 26 Feb for the armhf debian image?:
linux-image-2.6.31.14.27-efikamx_2012.02_armhf.deb

Should we replace the latter with your kernel even though yours is armel?
(Sorry if this is a stupid question, I am just getting started with this machine...)

TIA

I will provide an armhf one tomorrow at the latest, please stay tuned as more stuff is on the way :)

I am using the smarttops to run openCV for a research project. I do not know much about linux under the hood, so please forgive my ignorance. The smarttop I have is running out-of-the-box maverick, and it fails to boot in the way described above.

How can I install the hacked kernel via an sd card? I have a mac.

The SmartTop I got this past summer would not boot at all. When Genesi checked it was discovered it was shipped from the wrong bin. After a couple weeks they sent an SD image, which when I loaded it and rebooted the machine came up and has run perfect since then.

And I use PowerPC Macs...

If so, then why is this ratio zero on most modern computer software?
