I still have a /.dev/ laying around which contains my old pre-udev /dev/, but I guess I can throw it away now. Admar

showstoppers when moving from kernel 2.4 to 2.6
Hi, I have two issues after switching from kernel 2.4.x to 2.6.x First: Keymap. this issue is known, http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=269405 For 2.6 a workaround is not to load any keymap. 2.4 I was not able to test due to because I ran into a problem with the silo.conf (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=282965) but I will test tomorrow. Second: Problem with afbinit, which is needed to use AFB-based graphics adaptor. /etc/init.d/afbinit tries to parse the output of dmesg to determin which devices needs to be initialized. 2.4: has this output: fb0: Elite 3D at 01fc type 39 DAC 0 2.6: ffb: AFB at 01fc type 39 DAC 10 /etc/init.d/afbinit is looking for "Elite 3D" which is no longer reported by 2.6. ok can be worked around, but 2.6 does no longer report the devicename (fb0 in this example). Does anyone know a possibility to get the devicename? -- Jörg Friedrich There are only 10 types of people: Those who understand binary and those who don't.
