[maemo-developers] N810 Resets

[From: Alex Iliadis]

After running again my code and introducing a small delay factor, I noticed 
the following warning in ksyslogd saved logfile:

WARNING: prism_softmac_frame_tx_done() returned an empty frame

This was the last thing that was in the log prior the crash. I was indeed 
sending data at that moment so the wireless card was in use, and offcourse 
that's when the device rebooted on it's own. Without trying to speculate 
anything I believe this bug was introduced recently as my code works 
perfectly with the N800, latest OS2007.
