Buffer I/O error on device mtdblock2

[setti]

Hi,

I did an upgrade of uboot from within chroot environment, because i only could boot into rescue (i dont remember anymore why).
The upgrade of uboot seemed to be successfull (netconsole looks different know).
But i still cant boot my (in chroot also updated kernel linux-kirkwood 3.5.2) and get alot of these error messages in my kernel netconsole:

I only get into rescue. What is the trick to boot my normal system?
Im running archlinux also on my desktop pc and beeing no linux newbie, but this problem seems to be to big for me ;(

I'd look at erasing your NAND completely, checking & remapping bad blocks if any with special soft (probably NAND type dependent), then possibly reformatting the NAND into partitions, flushing the original Pogo OS image to it (see threads here) and then reinstalling Uboot.

[WarheadsSE]

Actually, Wiping your NAND entirely, is likely not the solution.

This shouldn't be stopping you from booting entirely however.

$this->bbcode_second_pass_quote('WarheadsSE', 'A')ctually, Wiping your NAND entirely, is likely not the solution.

fixed it my self.

in uboot i had to enter
$this->bbcode_second_pass_code('', 'setenv arcNumber 3089; saveenv') as it was yet set to 2097.

and i had to remve /boot/uInitrd because with this file existing i did not get into my usb hdd, but only into ubit-v6.

no more bad blocks warning now.

Question which still remeans: Can i ignore uboot warning about not finding uInitrd? Or should i investigate on how to create a working uInitrd?

[WarheadsSE]

It's not a required item. It is there in case you wish to use it. Ignore them unless you are intending to use a uInitrd.

How do you explain I/O errors disappearing?

[WarheadsSE]

Rather easily. The NAND maps are different across the devices.
