I'd still try routeirq and disabling PNPACPI though. My understanding that i8042 is not a standalone piece nowadays and is usally part of a kitchen sink^W^W SuperIO microcontroller which has to be properly setup by BIOS before kernel can access the part that emulates i8042. It looks that in some cases ACPI(?) misses this step and when i8042.c tries to restore KBC parameters it fails to respond. But I am not sure. -- Dmitry ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
