Strange image on shutdown , a Framebuffer problem?

After upgrade on kernel 2.6.30 a strange image appears on system shutdown.
Is some like a crossed bars or a bad framebuffer error.
Using different framebuffer start topics in kernel parameters the error persist.
Anyone Knows what happen....

Thanks.

If it ain't broke, broke it then fix it.

I use arch X86_64 , a 1280x1024 screen and gnome desktop.

Disabling framebuffer -> No vga mode in kernel settings shutdown screen goes black, no letters:
kernel /boot/vmlinuz26 root=/dev/sda6 ro

With framebuffer mode vga=791 or different modes: 790, 793, 788, 794, 789, 792, 795 ...
kernel /boot/vmlinuz26 root=/dev/sda6 ro vga=791
It appears a coloured screen with a corrupted image.

Re: Strange image on shutdown , a Framebuffer problem?

Solved after various changes checking new framebuffer settings at boot.

#  FRAMEBUFFER RESOLUTION SETTINGS
#     +-------------------------------------------------+
#          | 640x480        800x600         1024x768    1280x1024
#      ----+--------------------------------------------
#      256 | 0x301=769  0x303=771  0x305=773   0x307=775
#      32K | 0x310=784  0x313=787  0x316=790   0x319=793
#      64K | 0x311=785  0x314=788  0x317=791   0x31A=794
#      16M | 0x312=786  0x315=789  0x318=792   0x31B=795
#     +-------------------------------------------------+
#  for more details and different resolutions see
#  http://wiki.archlinux.org/index.php/GRU … Resolution

Now looks perfectly.

After some shutdown / reboots the problem persists.

Ok Loafer, but i think every screen needs diferrent issues.
Mine is LCD HP vs19b 19" screen
Allway works ok before kernel 2.30 with kernel paramethers: "vga=791"  but with kernel 2.30 the problem appears.

Now i was triyng with vga=775 vga=793 vga=794 and vga=795    Then vga=793 and vga=795 works better.

Afer sme shutdown / reboots the problem persists.
