Here are the links for the defects mentioned against au196 build on XO-1.5.
- Chat is very chatty on the network:
- ARP requests do not wake a laptop from suspend-resume:
- Regular “mdns” broadcasts keep waking laptops up:
- Physics on Tank: Still have the issue of when I draw lines that I see
the cursor trail but does not construct a line -
- Arithmetic on Tank: it is annoying that I have to wait for several
seconds after I enter an answer and it tells me it is correct before it
goes to the next question: http://dev.laptop.org.au/issues/1150
