I got a kernel Oops in __wake_up_common while receiving a file on my notebook via irda from a Pocket PC with 'ircp -r' (sending files to the PocketPC works). My System: Acer Extensa 3002 WLMi notebook Debian unstable/testing and irda-utils 0.9.18-3 linux-2.6.18 (from kernel.org) Irda (FIR) device is identified as NSC Vishay TFDS-6500. Resources have been identified from windows hardware manager: base 0x2F8, irq 3, dma 1. After first catching the Oops with a 'homemade' kernel (suspend2, ...), I compiled the same version without any patches.
