 |
|
Hi,
I have updated the kernel on both of my gentoo pcs to the latest ~arch version (2.6.21-r5 at the time of writing). This required me to unmask and install the ~arch version of splashutils (1.4.2). I also installed the 2007.0 livecd splash screens.
On my pc everything works as it did before the upgrade. On my laptop however I cannot use fbsplash. If I have fbsplash enabled then my laptop will boot ok into Xorg but I cannot switch it to any of the consoles using CTRL+ALT+F[0-6] or boot in verbose mode using F2. I also cannot shut down my laptop since that switches to fbsplash to display progress when shutting down. Whenever I try to do any of these things my laptop crashes and this error is displayed in the logs:
| Code: | Jun 12 00:01:01 [kernel] BUG: unable to handle kernel paging request at virtual address e162d000
Jun 12 00:01:01 [kernel] printing eip:

Does anyone know what the above error means and how I might go about solving it? The virtual address is always the same (e162d000 - possibly an access to the graphics hardware?) but the other values change. I take it these are memory addresses?
/etc/lilo.conf

My laptop is an x86 Pentium 3 900Mhz with 512MB RAM and integrated Savage MX/IX graphics. I am using the vesafb-tng framebuffer driver. My desktop PC is an Athlon64 X2 4800+ with 2GB RAM and an nVidia GeForce 7800 GTX graphics card. Since it is an amd64 I am using the vesafb framebuffer driver. Both are using gcc 4.1.2 and glibc 2.5-r3.
Thanks in advance for any help. |

I've just upgraded my laptop to suspend2-sources-2.6.21-r6 (I take it this is the version you were meaning - 2.6.22 isn't out yet). The symptoms with this kernel are exactly the same.
However changing the "append=..." line in /etc/lilo.conf to use a 16-bit framebuffer instead of a 24-bit one fixes this. I think the new Gentoo livecd-2007.0 fbsplash theme (or the new splashutils) requires more ram than my laptop graphics card has (16 meg shared) to use 24-bit colour on the console. Can anyone confirm this? |
