[Linux-fbdev-devel] Oops in atyfb

[Felipe C. <al5...@ma...>]

Hi,

Since in 2.4 kernels I've never had exit with atyfb I'm tring with new
kernels. I've not had success, however, I've found an oops in 2.5.5-dj1 and
some others dj kernels that might help tracking some problems. Here it is:

atyfb: using auxiliary register aperture
atyfb: 3D RAGE Mobility (PCI) [0x4c4d rev 0x64] 8M SDRAM, 29.4989 MHz XTAL, 230 MHz PLL, 50 MHz MCLK

ksymoops 2.4.3 on i686 2.5.5-dj1.  Options used
     -V (specified)
     -K (specified)
     -L (specified)
     -O (specified)
     -m /usr/src/linux/System.map (default)
     -S

Unable to handle kernel NULL pointer dereference at virtual address 00000000
