I have Multiboot kernel power and am using NITDROID with MAEMO.
The multiboot Countdown Timer never times out ( ZERO) rather the phone turns off as soon as the timer reaches Seven.

I tried reinstalling the Kernel, modules, multiboot but didn't help.

Please Help

It seems that a WatchDog timer is expired.

Matan's u-boot has a watchdog management but it seems that on your phone is not working.

Which HW version you have ?

You can see with cat /proc/cpuinfo from a xterm console.

Matan's u-boot is 100% compatible only with rev 2101

You can try the more recent Pali's u-boot version : http://talk.maemo.org/showpost.php?p...7&postcount=58
But unfortunately it seems that it is for rev 2101 also

My HW Version is 2204. I just purchased this handset in Feb, 2011

Also before replacing the Power kernel boot file with the one you provided i had this issue. I could never Timeout.
I tried to Reinstall the Multiboot Kernel, Modules but no help
Also reinstalled the Power Kernel 48 but no help.

Ops I misread you talk about countdown on multiboot menu and not countdown on u-boot menu.

N900 has some hardware watchdog.
If software not reset some Hw register every x seconds, N900 will be rebooted (or powered off).
This prevents software stalls, if Maemo hangs then it stops to reset the watchdog register and so watchdog will reboot N900 to exit the blocked state.

Watchdog timers are near 30 sec.

Multiboot during boot process loads a watchdog handler to avoid watchdog reboots, but in your phone this process seems to fail.

Any suggestions or reinstalls i need to do? Becuase i any how want to run Meego on my handset along with the existing NITDROID

As i informed i just bought it in Feb, 2011 hence not much time i could enjoy it. so would like to have different OS keeping my phone more alive.

Why do you wait that countdown reaches zero ?

I replaced the kernel 48 with the uboot prebuild you provided in the below thread

To enter the U Boot i need to Restart under Power Kernel 48 and keep my keyboard open and wait unitll timer is out, right?

Just type the single digit number in Front of the multiboot entry probably called:
"Maemo kernel-power 2.6.28.10-power48"

that will boot maemo with kernel 48.
i have added the uboot to kernel 48. and as per fabry i need not select maemo kernel power 2.6.28.10 power48 but rather wait for it to load by default since i restarted under it

Then you should simply start with the keyboard not visible.
