Yup, I had this about a few weeks also. I stopped testing for now. The l2 fix will reboot with an empty battery message.

zImage3 is working. And I got three OSes running. So for now I am ok. But I was wondering that when we can have more partitions, can we have more OSes? Now we are limited to three. There is also an Easy Debian package that starts a Debian OS using chroot (http://talk.maemo.org/showthread.php?t=85878)

Would it not be cool to have that as a fourth OS?

Seems like every N9 is also a bit unique in its behaviour (like the N900).

Exactly why I set up my mmcblk with more (even more

partitions! Did not yet have time to play with...

Just install your android on /home/ as usual, install Nemo on mmcblkp04 as usual and you are done

Is that also possible, if i have a bigger Swap on mtd-4 ?

The path shouldnt wrong, because android can bootup everytime, then kernel is same directory with Harmattan /boot/, I GUESS something in Harmattan, maybe some tunning or mod, make my Harmattan cant bootup. I dont want to reflash to try

This "recharge battery problem" seems to affect some users, I wonder if the N9's are so individual really??

The problem propably is that when the kexec() to the 2nd stage kernel is done the BME is left in some uninitialized state. This again could confuse the charging logic of Harmattan which performs an emergency shutdown...
It seems to require some debugging to find out why this affects only some devices.

Could it have something to do with N9 HW revision?
For example, my device is 64G rev.1501

If your swap is on mtd4, just use the ubiboot version that installs on mtd5.

So let us collect the infos:
mine is a 64GB rev. 1601 with (almost) zero problems.
Swiss firmware, highest PR of all

Sometimes I do need a few boots, until Harmattan comes up. Maybe due to this bug, also? But I have never seen such message. I guess on wrong bootreason passed to second kernel?

Code:

~# cat /proc/cpuinfo | grep Revision
Revision        : 1501

No issues other than the first time booting into all OSes which has to be done via telnet. Subsequent attempts pass without any issues.

Using mtd4 swap and mtd5 ubiboot...
