[HELP] Guruplug bricked after kernel upgrade

[radael]

I read the forums for 4 days.  Tried four different ways to fix my kernel.  We are not the only ones.

Hi,

 Here is the bootlog right now, any clue?

 Seems that is not able to find any OS, isn't it?. Is there any reliable way of having a guruplug exactly as a new guruplug?

Looks like the root file system has a problem.

Yes, in this step I got an error starting the tftp but I thought that something was wrong in my uboot.

I've had this error message in the past

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

what it was for me was that I had not selected the following option in menuconfig during the build;

File Systems --> Miscellaneous File Systems -->  UBIFS file system support

Make sure it is built into the Kernel (i.e. showing

• and not [M]) as the kernel needs it to read the file system

Could you tell me where are this options?  Regards.

[richard]

When you prepare the kernel for the build using

make ARCH=arm menuconfig

Follow one of the building kernel wikis

I had the same errors when booting from an external hard disk, before using rootwait in the bootargs.  But, since you are trying to boot from flash, this should not be a problem.

If you have not compiled your own kernel, then the one you are using should already support ubifs.  Your U-boot variables support it:

     x_bootargs_root=ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs

Hi,

 Have it fixed. I will post the process, I don't have time right now!. Thanks to all the people who helped documenting different processes to return zombie plugs back to life!

Hi,

 Finally, I was able to get my guruplug working again. I was having an error tftf'ing the rootfs file, but it was due to the incorrect tftp version installed on the server. As it's a big file, the standard tftp failed, so I had to install another tftp server application, as read somewhere in the forum.
 After reinstalling the system, some modules of a newer kernel were needed, so I scp'ed them. Now it boots the newer kernel (Linux guruplug-debian 2.6.33.7), and the best of all is that Zoneminder now is working much better, with cpu loads less than half. I do not know what's the cause of it, but each zmc process was dragging about 23% of cpu before the 'accidental kernel upgrade', and now is consistently ~6%. The load in the ZM console is ~0.1%!!!!!

 I want to thank all the users that pointed me to the correct path to get my guruplug back to life (specially radael & richard).

 I have also written a process to get Zoneminder working from scratch, so if anyone is interested, ask for it using PM.

 Thanks again,

PacoLM

Again, you are too kind, PacoLM.  Mostly we only encourage.

It might help others if you were to make a wiki page about Zoneminder.

Just go to page   http://plugcomputer.org/plugwiki/index.php/ZoneMinder, and use the "create" button at the top of the page.  Just be sure to add these lines to the bottom of the page:
