reboot problem

[funnyman]

Hello, I have problem with rebooting raspberry. For "reboot", it disconnects ssh and LAN stops flashing, then it looks like strating again (led started to flash, discs starts running. Hovewer, I can't ssh to raspberry and it doesnt respond to ping, I have to unplug power and plug it back, then raspberry boots properly.
Please help.

Did you sync before reboot?

[funnyman]

if you mean writing "sync" to terminal and then writing reboot, then, yes.

sync and reboot -f also doesnt work.
it ends like this:
$this->bbcode_second_pass_code('', '[root@alarmpi ~]# reboot -f
Rebooting.
2013 May 31 00:29:36 alarmpi [ 281.005888] Restarting system.')
and then its stuck

Do you use overclocking and if, is it the same effect with default values?

[funnyman]

I don't use overclocking.

I only upgraded, installed samba, noip, mc and transmission, added some users and that's all.
Hence upgrade was the first think which I do, I don't know if it was okay before it.

But, I also changed distribution of RAM, for GPU I use 48MB. With lower, it didn't start at all. I'm going to try another setting.
I reset config.txt to factory settings. No effect

but why it boots properlly when I do "hard" restart, with unplug and plug in usb power cable..? And what should I do, when I have no backup? repartition and then don't upgrade?
It's crucial for me, because I have limited possibility of reaching Raspberry physically, I installed watchdog on it, but it hangs up, when watchdog tries to reboot. And I need to do reboot over ssh...

Should installing another system, like raspbian, solve this problem..?

The firmware is the same across the distributions.

I'm using power supply ordered with raspberry.
Trying my mobile charger makes no change.
