Cant boot after update

[Rharris118]

Last night/early hours of this morning, i checked for updates on my fedora 11 system, i had 71, so i thought nothing of it and just updated everything. i restarted only to find i couldnt boot, it gets past the blue/white bar loading towards fedora 10.92 then i get a page full of
init: tty4 main process ended, respawning
init: tty5 main process (2558) terminating with status 127

then a few more tty numbers and processes, then
various tty numbers (that were listed above) respawning too fast, stopping

anybody able to help me out?

many thanks!

EDIT:
ive just pressed f8 on booting to get into the boot menu, and found 2 different selections, so ive booted into the other one and can get to the login screen!
problem is, the mouse or keyboard arent working now! :(

the selections i have in grub are:
fedora (2.6.29.1-70.fc11.i686.PAE)
fedora (2.6.29.1-68.fc11.i686.PAE)

im just snooping around in grub, and looking at the names of files, the kernel its using now is i686.PAE, im sure it wasnt this before, it was i586 could this have done anything?

What video chipset do you have. I can't boot a PAE kernel to save my life. Always locks up right when X is starting.

Its an acer 5920G laptop, nvidia 8600M GS.
Could be that, im sure it wasnt a PAE before...when i boot the second option i get into the fedora GUI login screen, its not crashed because the carrot (correct term?) is blinking away in the password field...

Prior to the beta release, all I would have after an install was the PAE kernel because I have 4gb of RAM. With the beta, at least I now get the i586 kernel as well. I would prefer a functioning PAE kernel, but it seems I may be waiting until RC...

ive formatted and reinstalled fedora...i installed from the local cd rather than downloading all the updates during install. its updating now, ive just seen the PAE kernal installing, does this mean when i restart its going to be the same thing again???

Check your /etc/grub.conf and see if the i586 kernel is also installed. If it is, just change the default setting from 0 to 2 or whatever number corresponds to the i586 kernel.
