Subjectscheduling while atomic in visor/serial (2.6.8.1-mm4)
From
Hi USB Gurus!

Since several kernel revisions I get hurt by a
scheduling while atomic!
when doing transfers via usb to my palm:

bad: scheduling while atomic!

visor ttyUSB1: visor_unthrottle - failed submitting read urb, error -1


I already have asked this once but since then nothing has changed. So
are there any chances to get this fixed?

Best wishes

Norbert

STURRY (n.,vb.)
A token run. Pedestrians who have chosen to cross a road immediately
in front of an approaching vehicle generally give a little wave and
break into a sturry. This gives the impression of hurrying without
having any practical effect on their speed whatsoever.
