system not booting after modprobe

I followed the instructions here:

http://www.linuxquestions.org/quest...ad.php?t=344884

in order for my ubuntu system to recognise my tv card.I succesfully
bought up tvtime and tuned into a few channels - all fine.

The system was working fine.

Following a power down and restart however, the system reaches a certain
point in startup and the screen listing modules being loaded just starts
scrolling up as if the ENTER key was held down. The X Windows clears the
screen and hangs : no logon. I switch to a text terminal ctl-alt-f1 and
can see my breezy prompt, but again its is scrolling : something in the
device drivers is injecting what appears to be CR/LF into the tty/stdin.

I can only boot into XP.

Any suggestions on how I can rewind the system from either (a) XP -and
then I will need to somehow see the ext3 file system , or (b) from a DVD
boot of knoppix.

All help gratefully received : I have no idea of what the modprobe has
affected and am totally unable to log into my system in any mode whatsoever.

regards.

Since the only permanent change you made was the creation of a file
under /etc/modprobe.d, I'd boot the system in single user mode and
remove or move it out of there.

Think it might have been created correctly? You didn't save the file
as cx88xx I hope?

Mucking with the kernel or its modules can get you into trouble. You
really need to know what you're doing, and do it correctly (measure
twice cut once kind of approach). I'd suggest going over each step in
the procedure, using man <command> <switches>, to gain an
understanding on what each step really is doing.

Have you tried removing the card to see if you can get control booting
again?

I remember reading about some sort of rollback function in something.
Perhaps you can roll back the driver or maybe locate one of it's files and
experiment.

At least computers aren't built like they build cars. If so, we would have
to have an 80 pound tool chest and to get at the cards, you would have to
get at the motherboard.

I had the same odd keyboard behavior as you except it was in windows today,
I had something under the keyboard enter switch, and it was just Happening
to stick at certain times.
