Subject2.6.0-test2 does not boot with matroxfb
From
Date
I tried on my PC with a Matrox-G450 several kernel and boot options.
Every time when the console should work with matrox framebuffer, linux
was crashed. With 2.6.0-test2 and 2.6.0-test2-bk7 I had the following
warning performing ''make modules_install''
WARNING:
/lib/modules/2.6.0-test2[-bk7]/kernel/drivers/video/matrox/matroxfb_crtc2.ko needs unknown symbol matroxfb_enable_irq
This WARNING disapears for 2.6.0-test2-mm5. But also 2.6.0-test2-mm5
does not work with framebuffer. I tested the following combinations of
parameters:

|VGA = 6 | VGA = 775 |
| | |video=matrox:
| | | vesa:0x31C
----------------------------+---------+---------------+---------------
2.4.22-pre6-ac1 | | |
CONFIG_FB=y | VGA=6 | VGA=775 | vesa:0x31C
CONFIG_VIDEO_SELECT=y | | |
----------------------------+---------+---------------+---------------
2.6.0-test2 | |crashes |crashes
CONFIG_FRAMEBUFFER_CONSOLE=y| VGA=6 |after |after
CONFIG_VIDEO_SELECT=y | |BIOS DATA CHECK|BIOS DATA CHECK
----------------------------+---------+---------------+---------------
2.6.0-test2 | | |
CONFIG_FRAMEBUFFER_CONSOLE=y| 640x480 | 640x480 | 640x480
CONFIG_VIDEO_SELECT=n | | |
----------------------------+---------+---------------+---------------
2.6.0-test2 | |crashes |crashes
without console-fb | VGA=6 |after |after
CONFIG_VIDEO_SELECT=y | |BIOS DATA CHECK|BIOS DATA CHECK
----------------------------+---------+---------------+---------------
2.6.0-test2 | | |
without console-fb | 640x480 | 640x480 | 640x480
CONFIG_VIDEO_SELECT=n | | |
----------------------------+---------+---------------+---------------
2.6.0-test2-bk7 | |crashes |crashes
with console-fb | VGA=6 |after |after
CONFIG_VIDEO_SELECT=y | |BIOS DATA CHECK|BIOS DATA CHECK
----------------------------+---------+---------------+---------------
2.6.0-test2-mm5 | |crashes |crashes
CONFIG_FRAMEBUFFER_CONSOLE=y| VGA=6 |after |after
CONFIG_VIDEO_SELECT=y | |BIOS DATA CHECK|BIOS DATA CHECK
----------------------------+---------+---------------+---------------

Because I am afraid, that the lines of the table are wrapped by the mail
client, the is alsa attached to this mail. Any hint would very much
appreciated.
