Hello!
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.
Oops:
acer01:~# ircp -r
Waiting for incoming connection
srv_obex_event(): Link error

I tried to debug the Oops with 'echo 4 > /proc/sys/net/irda/debug'
previous to 'ircp -r'. After the Oops I've stopped the debug output with
'echo 0 > /proc/sys/net/irda/debug'. Then I've extraced the sequence
from /var/log/kern.log
See: http://www.uni-koeln.de/~a0537/irda_debug.log
