No console on Riva TNT since 2.6.26-0.rc4

No console on Riva TNT since 2.6.26-0.rc4

[Quel Qun]

Hi,

The system boots fine with 2.6.26-0.rc3.1mnb (Mandriva Cooker), but since rc4, I see a few squares of color, then a black screen and the console never comes back. This is independent of the resolution chosen when using vga=ask. The machine does boot and I can start X if I log in blindly. Only the F1 to F6 consoles are gone.

Bug originally reported and ignored on Cooker: https://qa.mandriva.com/show_bug.cgi?id=41302

My card is an old STB NVidia Riva TNT, monitor is a flat panel Dell 2007FP, system is a Dell Dimension XPS T600 (82371AB/EB/MB PIIX4 with PIII 600).

I cannot see anything different in /var/log/messages between rc3 and rc4 (vga=837)

vesafb: framebuffer at 0xfc000000, mapped to 0xd8880000, using 7500k, total

This is still true with a vanilla 2.6.26-rc8.

$ grep FB_RIVA /boot/config
CONFIG_FB_RIVA=m
# CONFIG_FB_RIVA_I2C is not set
# CONFIG_FB_RIVA_DEBUG is not set
CONFIG_FB_RIVA_BACKLIGHT=y

Please cc me if you need more info since I am not subscribed to the kernel list.
Thank you.

Let's cc the fbdev list.

Is this a regression?  Was 2.6.25 OK?

Thanks.

2.6.26-rc3 was OK. -rc4 wasn't.
