@ moderators : I can't edit my message so I started a new reply to continue writing.
So I extracted again my old working backup and this time I upgraded the kernel to the latest version 2.6.39.2 and after I did the necessary apt-get updates and dist-upgrades I rebooted to check if the problem remains but this time it worked. And until now I haven't got any problems. I think that the problem was that the old kernel I was using was not working well with the new wheezy philosophy.

I extracted an old backup I had from 3/2011 and worked fine with debian wheezy. I also rebooted 2 times and the plug was workink ok from sd card. After that I did apt-get update with 195 updates and after that a apt-get dist upgrade. And then after a reboot the same messages but without warnings about the new /run directory because after the updates the /run was there. So again I couldn't boot from sd card and the boot process was stoping with the message "unable to receive ctrl connection: Function not implemented".. below is the boot proccess ... __ __ _ _ | \/ | __ _ _ ____ _____| | | | |\/| |/ _` | '__\ \ / / _ \ | | | | | | (_| | | \ V / __/ | | |_| |_|\__,_|_| \_/ \___|_|_| _ _ ____ _ | | | | | __ ) ___ ___ | |_ | | | |___| _ \ / _ \ / _ \| __| | |_| |___| |_) | (_) | (_) | |_ \___/ |____/ \___/ \___/ \__| ** MARVELL BOARD: SHEEVA PLUG LE

I renamed the /dev/.udevd from the SD to /dev/.1udev-for-delete added the following line to /fstab tmpfs /run tmpfs nodev,nosuid,size=100M,mode=0755 0 0 Rebooted the plug but with no luck Starting the hotplug events dispatcher: udevdudevd[589]: error: runtime directory '/run/udev' not writable, for now falling back to '/dev/.udev'
. Synthesizing the initial hotplug events...done. Waiting for /dev to be fully populated...udevd[590]: unable to receive ctrl connection: Function not implemented
udevd[590]: unable to receive ctrl connection: Function not implemented After that I created the /run directory to the sd card and again the same bad luck... From the http://wiki.debian.org/ReleaseGoals/RunDirectory#Packages_using_.2BAC8-dev.2BAC8..2Ait says : /dev/.udev/, v167+ will automatically use /run/udev if /run is available and writable. (168-2 available from unstable)and from http://wiki.debian.org/ReleaseGoals/RunDirectory#How_to_transition_from_.2BAC8-dev.2C_.2BAC8-dev.2BAC8-shm_or_.2BAC8-etc_to_.2BAC8-run.3Fsays that : All users must transition to /run for wheezy .... 1 Depend on initscripts (>= 2.88dsf-13.3) 2 Replace all usage of /dev/.* /dev/shm/.* or etc with /run 3 Move all files in /dev/.* /dev/shm/.* or etc to /run in the package postinst ... If you need to use /run in the early initramfs, you'll need to support both /run and the existing /dev/.xxx as a fallback:WTF? Can we use a symlink to temporary resolve this??

I've been running almost two years sheeva plug from sd card and suddenly I noticed some kernel i/o errors. FYI I'm running Debian testing... I booted from nand and fsck the sd card with many errors so I proceeded with fdisk and extracted a backup I had from last month to the sd card. e2fsck says that mmcblk0p1 (kernel uimage) and mmcblk0p2(rootfs) are ok But when i'm trying to boot from sd-card I get a "udevd[596]: error: runtime directory '/run/udev' not writable, for now falling back to '/dev/.udev"and after that I get stuck to the error : Waiting for /dev to be fully populated...udevd[597]: unable to receive ctrl connection: Function not implemented udevd[597]: unable to receive ctrl connection: Function not implementedCan someone help to resolve this or is my sd-card almost dead ? Below is the serial console print when I try to boot from sd card (mmc). Marvell>> boot SDHC found.

Hardware and U-Boot firmware / Hardware / Re: Poll: What is the status of your SheevaPlug's Power Supply?

I had a power supply failure and replaced it with a switced 5v-24v / 3A external p.s and the plug comp. is running fine until now. After I replaced it I noticed that the plug was running faster (faster boot time, remote response, iceweasel page draw etc). I also have connected a usb powered 500GB disk, but it's covered by the plug's usb output. Another thing that I posted on another thread is : Why when I'm using an external 5v/3A power supply it's relatively cool or warm but when I was using my plug's original power supply (which is dead now) it was so hot that sometimes you could not touch the little metal case? The answer is : because the plug's original power supply is for trash. So the best thing to do is to replace it as soon as possible....

I'm a happy plug computer addict with external power supply, and it's working fine until now(fingers crossed). So I think that the right question is: Why when I'm using an external 5v/3A power supply it's relatively cool or warm but when I was using my plug's original power supply (which is dead now) it was so hot that sometimes you could not touch the little metal case?

I found an old cpu heat sink and after I cut it a little it was a perfect fit for my sheeva plug. Except for the thermal silicon paste I also used a plastic cord to tighten the heat sink, I placed it on the side of the leds, where the cpu is located to put more pressure to the heat sink on the cpu, this plastic cord can hold 85 celcius so I think that it won't melt. The only problem that I was worrying was that the metal heat spreader on top of sheeva board has a little curve so the heat sink wasn't fitting perfectly so I putted a lot of thermal silicon paste to fill the gaps. Now with a normal use the heat sink is heating a little but when the plug runs with a big cpu load then the heat sink is getting very hot, and this means that it's working. I'm glad that I helped my little beloved plug to cool down and feel better, also my sd card now is very cool. As you can see on the pictures I didn't bother to put the other half of the plug and left it open for the air to flow (especially between the psu and the board), it' s more cool that way.

to alessio I wanted to do something similar to your solution for my sheevaplug. In a previous post you attached some pictures and I have some questions. In the first picture that shows the original metallic heat spreader attached on top of the mainboard , it seems that the cavities (where the metal attaches on the chip or the memory modules ) are filled with some metal pieces. Did you put those metal pieces or they are from the manufacturer? cause mine metal spreader has those cavities so I must fill the up with some metal and not only with glue. And the other question is for the heat sink, is it safe to put only glue to firmly connect the extra heat sink with out worry that it will fall apart? or we can use something else to tighten it more firmly. In a previous post in the same thread, jiinx used plastic cords to tight the heat sink (and attached some pictures), is it dangerous for that plastic to melt down or it can hold to the temperatures that the plug produces? Thanx in advance...

I opened my sheevaplug and made some holes on the plastic case for the metal heat spreader to breathe but I found out that the heat is relatively high again especially in the summer hot days. I think that the only way to keep the plug cooler is to replace the power supply with an external one. Having in mind that many sheeva users have dead and melted power supplies and that generally heat is very bad for the life of chips, I 'm allready searching for a new 5V 3A (based on the sheevaplug specs) power supply.
