Everything works fine with kernel-2.6.9-1.667 However all of the 2.6.10 kernels I have tried from devel have given the "i8042.c: Can't read CTR while initializing i8042" error during the boot process and the keyboard doesn't work. Booting with acpi=off solves the problem but given that this is a laptop (Dell Inspiron 5150) this seems less than ideal. Any ideas?
