cannot reboot my laptop after kernel upgrade

I just upgraded my laptop to linux-2.6.16 today, since felt like I was over due for a kernel upgrade (and I was trying to put off doing something else ;) )

Now when I reboot with 'init 6' like I always do, it will go though the motions but when it get's to the end, it will just power down the monitor, nothing else. The only way I can get it out of this state is to hold down the power button and turn it back on.

I know very little about hardware, so I don't even know what to search for. Is it a power management issue maybe? I would provide more info, but that would mean I actually knew what was going on. :)

Can anyone point me in the right direction?

Thanks!

it will power down the monitor? or it will show a black screen? -- the back screen is a common problem that you can fix it enabling the frame buffer support in the .config file (there is a threat about this).

Thanks for the reply! I think there might be more to it then that because the computer will actually not reboot. Also, my FB device seems to be working fine. 1024x768, Linux logo and all. Like I said, hardware is my least knowledgable subject, so I could be way off on this, but I didn't think my display device would prevent my computer from restarting.

**edit**
The best way I can describe what's happening is like it goes into suspend instead of rebooting. My LED ligts still show the computer is on, but it's not doing anything.

As for the rebooting issue, I had the same thing happen after my last kernel upgrade. I can put in my live-cd which runs the same kernel version (2.6.16.16) and the system reboots when I tell it to. It has to be a kernel config issue, but I don't know which area to tell you to look at. Besides, this is linux. We aren't supposed to reboot! ;)

My guess would be the power management, but I haven't worried about fixing this system yet since I shut it down at night.

EDIT: fixed quote.

This happened to me recently on my ancient laptop and I am trying to remember what I did to fix it!
(I had not even upgraded anything)
I think I had been fiddling with the Kde Power control>Laptop Battery applet.
I think I fixed it by turning the apm power management stuff off in the bios. this enabled me to boot and undo whatever I had done in Power control.
This may be irrelevant to you drkstr, but I just thought I would mention it..

Since you say you upgraded the kernel, are you sure that all the modules are there for the laptop that you had for the old kernel?

Which do you have, APM or APCI installed?

oops, I thought I posted the hardware in my first post, but I must have forgoten.
It's a sony VIO (from around 2001 I think) That's all I really know about it.
