6 No-one can say that, the driver is buggy. Something to do with waking the card
7 up or bringing it out of deep sleep. Personally, I think it's along the lines
8 of a race condition in how the card is reliably powered up (but that's just
9 be thinking of what's most likely). Intel has a bugzilla, which shows that
10 virtually every distro on all platforms using the 3945 have the identical
11 problem in every kernel version that contains this code:

15 We have two options:
16
17 - get involved, fix it ourselves, submit patch to upstream (intel)
18 - wait for intel to come up with reliable code

20 All the evidence points to intel taking this seriously, it's a popular card
21 and intel wants their stuff to work nicely on linux. So chances are it's a
22 deeper problem that it appears on the surface
