Default And what about 2.6.7?

Hi.
Anybody know what has changed between 2.6.6 and 2.6.7-rc1 that might affect Nvidia drivers? In 2.6.6 everything works just fine, testing 2.6.7-rc1 entire computer just hangs...

(talking stock kernels here, straight from kernel.org)

Strange. I'm quite sure I didn't change anything in the config that should make any difference.

It seems like X starts allright, no errors in the log and so on. The only slight problem is that I can't see it, the screen is blank. And I can't change back to console tty either. Strange...

Try using the nvidia built-in AGP instead of the one built into the kernel, also you might want to disable ACPI and see if that helps any.

Ok. After checking logfiles a bit more I found this (from the moment that I started X in 2.6.7-rc1):

This is then repeated *loads* of times. Anyone can tell me what this is? Kernel bug?

I'd rather not test around with this any more til I know that It'll work. I was forced to hard reboot my computer, I don't like that at all...

Replying to myself. After looking at the kernel source it seems that this is Nvidias fault. Nvidias driver uses a function pci_find_subsys that according to comments in the code is deprecated. I'm no kernel coder but this seems like begging for trouble.

Anyone knows why this works for shassard but not for me?

Perhaps because shassard is using nVIDIA agp driver and you are using agpgart? This is a big ..perhaps..
Enable this by adding the driver option to your X config (in Device - where Driver "nvidia" is).
Option "NvAGP" "1"

Nope. Makes no difference.

I can add that 2.6.7-rc1 w/ nvidia 1.0-5336 works just fine for me. (I'm using agpgart.)

Both kernel and driver are unpatched.


Edit: minor correction

Default with 2.6.7-rc2 nvidia display is back

Display initialisation failed with Kernel 2.6.6-mm1 to 2.6.7-rc1-mm1 (all of them i tried) and nvidia 1.0-5336 drivers. whole system used to get stuck when nvidia drivers were initialised-strange screen seen with strange symbols-keyboad too dump and stuck-had to hard reboot.
but with 2.6.7-rc2 nvidia display is back .

too irresistible-kernel rebuilding-u r warned

Ho Hum, I just had a bad day of KMail crashing (hanging) the X Server every time I started it up. I was getting very similar messages in the system logs (this is with SuSE 9.1 kernel 2.6.4-54.5) ... see my new post for full details of that. I eventually recompiled the nvidia kernel module, forcing AGP down to 2x rather than the usual 4x , and so far it hasn't crashed again. Could be a kernel bug, could be an nvidia driver bug ..... could be both (look on the bright side )

Thankfully I have another machine from which I can ssh to the one which crashes ... killall -9 X is becoming all too common in my .bash_history
