Public bug reported:
Under kernel 2.6.17-7 my nvidia card operates correctly. Both the
nvidia and vesa drivers work. However on 2.6.17-8, 2.6.17-9 and
2.6.17-10 the card suffers a failure when gdm starts.
On kernels > 2.6.17-7 the system boots. usplash correctly draws the
startup graphic. When gdm starts the screen appears to "flash" white
and then go blank. The system is then unresponsive (as far as I can
tell) to keyboard input. It will not switch to a virtual terminal, nor
will the power key do an init 0 (or whatever it does for a soft
shutdown). The result is that I have to do a hard shutdown (hold down
power button for 5 seconds).
Currently I use the vesa driver. If I start kernel 2.6.17-7 everything
works as I expect. If I choose kernels 2.6.17-8 through 2.6.17-10 this
issue arises. The only configuration difference is the kernel.
The X logs do not suggest an issue. Furthermore a quick grep of
messages from running 2.6.17-7 and 2.6.17-8 only shows differences where
expected (such as amount of RAM freed after initrd).
