Problem Description:
When booting "init 3", the screen prints "ENTERING SLEEPING MODE" and i can't access to any console even by pressing keys.
When booting "init 5" Xorg starts nicely and works perfectly but when pressing CTRL-ALT-F[1-6], the same happens : the screen prints "Entering sleeping mode" and i am not able to see anything.
All the rest works perfectly so i can access on ssh to the box and i can see a new user with the "who" command when logging in on tty1.

Quoted 3 lines

Please let me know how to post attachment, i think my .config and others like "lspci -vvv" may be needed.

I don't understnad this report much, but it sounds like a very recent regression.

You're not actually trying to suspend the machine at the time, are you?

And it doesn't sound like the keyboard has malfunctioned?

Does anyone know where this "ENTERING SLEEPING MODE" message is coming from? A bit of googling makes me suspect that it is actually coming from your monitor, which perhaps indicates that the kernel is sending incorrect DPMS signalling to the monitor, or something like that?

I'm pretty sure he's not.

Correct. The 'tty' bit is misleading. He's not getting any visible text console when he hits ctrl-alt-f1 .. f6.

Almost certainly it's the monitor not being able to sync to the output when he's outside of X. Checking his lspci above, he has an intel chipset. Looking at the module loaded list, he does indeed have intelfb loaded. Checking the log from 2.6.23-rc6 to -rc7 shows four patches (at least) against intelfb. Those people implicated are on the
to: line now.

Patches included below for your reading pleasure, but gmail will almost certainly hork them up; sorry about that. If I had to guess, the one from Krzysztof (third down) seems the most likely culprit, but I'll let others with the big brains decide.

(Changesets pulled from mercurial, so they won't match up with git -- sorry. But there aren't that many patches from rc6 to rc7, so it shouldn't be hard to find these.)

intel-agp: Fix i830 mask variable that changed with G33 support

The mask on i830 should be 0x70 always, later chips 0xF0 should be okay.

Subject: [PATCH] Intel FB pixel clock calculation fix

Intel framebuffer mis-calculated pixel clocks.

The pixel clock (and thus both H and V sync) will be slower than requested, so if you set the minimum allowed the display may not sync. In case of really old CRT display it could theoretically damage it.

I'm using it with PAL TV (using RGB input - SCART connector) and the bug prevented it from working at all (TV requirements are more strict and made the bug visible).
