I'm not sure why it hangs, and I'm not very worried about it. Netbook releases are new, and I remember the same kinds of problems when Linux notebooks were new. I had one laptop that worked perfectly except for sound, the mouse, and networking. :-) The next release fixed all those. (Even now, I have a pair of old notebooks running Jaunty Jackalope because Karmic Koala won't run their fans. They overheat and shut themselves off within minutes.)
I even remember the problems when Unix PCs were new. I was in Dave Barach's living room, in 1983, when he got a call from our Maryland office, which had just received the editor Dave had sent them for our as-yet-unreleased PC/IX product, done under contract to IBM, which was to run on stock IBM PC/XTs.
I could only hear Dave's side of the conversation.
What do you mean, "The color's wrong"? What do you mean, "color"?
We'd never seen a PC with a color monitor. Weren't all displays monochromatic? Once we found out how they worked, Dave fixed the problem.I am, however, discomfitted by having to power-cycle a box -- I worry about unsynced disks and stuff. Luckily, some neuron fired and I remembered the magic SysRq key. I have had to use it so little, over the years, that I didn't remember any details, but Wikipedia came to my rescue. It does the trick, and lets me do a soft re-boot from my keyboard.
(My keyboard doesn't actually have a key labelled "SysRq," but Alt-"Print Scrn"-k works just as well.)
No muss, no fuss, no bad blocks. Magic.
Thrupence and sixpence every day.
