I'm experimenting PCI address space collisions on an ICOP PC104 VDX-6357 motherboard (with no cards/expansion at all) and kernels 2.6.33/34 collisions where not there with kernel 2.6.29 (I start with this .config and I've done a make oldconfig for 2.6.33/34). I have no ACPI support and I'm using the sisfb framebuffer on a XGI Technology Inc. (eXtreme Graphics Innovation) Volari Z7 chipset. thanks for any ideas Paolo here are some info: ------------------------------------------------------------------- cat /proc/cmdline ------------------------------------------------------------------- root=/dev/sda2 quiet video=sisfb:640x480-32 ar8.debug=1 ar8.outputs=0x80 BOOT_IMAGE=vmlinuz-2.6.33-r3-vdx ------------------------------------------------------------------- dmesg kernel 2.6.33: ------------------------------------------------------------------- Linux version 2.6.33-ibty3-vdx (root@nibble) (gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)) #22 Sun Mar 14 00:35:18 CET 2010 CPU: vendor_id 'Vortex86 SoC' unknown, using generic init.
