indeed, thanks for the info kyle. i've been avidly following the dev cycle of the software/hardware here, and it's good to see some technical info from the kernel ML, 95% of which is over my head would it be possible for someone - michael, kyle? - to give an update on this kind of info on a regular basis? i'm sure there are plenty of others eager for technical progress, but who are unlikely to venture on the kernel list? > Kyle Bassett wrote: > > I have been following the "Suspended Mode" thread in the kernel ML and > > they have made amazing progress within the last week.
