Hello,
This particular laptop has, among other things, an Athlon XP1800 mobile processor with an ALI USB 1.1 controller, an ATI Northbridge, an ATI 320 (CAB0) videocard and a synaptics PS/2 touchpad. In the following I'll try to best describe the problem I have. (Please note that I am not a developer, although I dream about writing a driver for the oz6912 PCMCIA controller this laptop came with).
Kernel versions covered: 2.4.19 - 2.4.21pre6 patched with acpi-patch. Distribution: none (LFS 4.0). For distributions, I tried RH 7.1, 7.3 and 8.0 but all fail installing if I don't pass pci=off during installation. After reboot and stock kernel I end up with the problem below, which does not dissappear when custom compiling the kernel.
1) I compiled the kernel with usb support built-in (not as modules). Upon booting and entering the login prompt, the keyboard is blocked (i.e. I can't write anything with it). If I press the power button, the computer enters runlevel 0 (so it is not frozen) and powers off.
2) Recompile the kernel with usb as modules (usbcore and usb-ohci) and do a script in /etc/rc.d/init.d/ to load the modules at boot time. Symptoms stay as above.
3) Remove the script from /etc/rc.d/rc3.d (e.g.). Boot. Login as root. The keyboard works (yee!). Do cat /dev/mouse. Keyboard no longer works (all three LEDs light up). Reboot.
4) Do step 3 above but don't cat the mouse anymore. Instead do modprobe usbcore and modprobe usb-ohci. The keyboard is NOT blocked. Do cat /dev/mouse. The mouse works (yee). Do mount -t usbdevfs none /proc/bus/usb. The USB filesystem is initialised and the USB works beautifully (tested with a digital camera, a scanner, and currently with an Apple USB mouse and Apple USB keyboard).
Did any1 have a similar problem? I posted this message about three months ago on the linux-usb, omnibook and finally last week on linux-laptop, with no success :-( At this point I am completely out of ideas, so I'd appreciate any help.
