In 2.6.22 we decided to disable PnP by default; it is apparently enabled now and fails to activte IrDA completely. So it moves to post-2.6.22 regressions :) let me know which information you need [ 2192.666450] pnp: PnP ACPI init [ 2192.666589] ACPI: bus type pnp registered [ 2192.686035] pnp: Device 00:0a activated.
